Thanks so much for taking the time to read this! 😊

In this article, I'm going to reveal some super amazing React application tips that will totally boost your performance and elevate your code-writing skills! I'll be sharing all the cool stuff I know and use, but if you have even more incredible tips, don't hesitate to drop them in the comment section below! Let's dive right in and rock this! 🎉

1. Custom Hooks: Custom hooks have this cool naming pattern: "useSomething" - so you know they're React hooks right away! You can whip them up using the built-in useState, useEffect, and useContext hooks. The best part? You can create reusable bits of logic that can be shared throughout your entire app! 🚀 So, go ahead and give Custom Hooks a try - you'll be amazed at how much they can boost your coding skills! Let's look at an example

    import { useState } from 'react'
    export const useCounter = () => {
        // this hook is to create a counter
   
        // First:  create our counter state
        const [counter, setCounter] = useState(0)
   
        // second: write the function to increment counter
        const handleIncrementCounter = (e: Event) => {
            e.preventDefault();
   
            setCounter((prev:boolean) => prev + 1);
        }
   
        // third: create a return statement. The return statement is used to                            define what the hook will return when the hook is called
        return { counter, handleIncrementCounter  }
    }
   

   Using it in our App.tsx file

    import React from 'react'
   
    const App = () => {
        const { counter, handleIncrementCounter } = useCounter();
        return (
            <>
                   <p>{counter}</p>
                   <button onClick={handleIncrementCounter}>
                        Increment Me!                             
                    </button>
            </>
        )
    }
   

   We just created a fun little counter app together! 😊

2. Code-Splitting and Lazy Loading: Code Splitting is a technique used in React to split the codebase into chunks that can be loaded on demand, instead of loading the entire application upfront. This will reduce the load time and overall performance of the application. This may be hard to understand so let me break it down by using an example or can I say code-split it 😅.

   So, imagine you're making an app with an admin page and a regular user page, right? You don't want users to load all the admin stuff they don't need, and the same goes for admins. That's where code-splitting comes in handy, my friend! 😄

   Let us see an example of how we can implement code splitting in React.

    import React, { lazy, Suspense } from 'react';
   
    const AdminPage = lazy(() => import('./AdminPage'));
    const RegularUserPage = lazy(() => import('./UserPage'));
   
    function App() {
      return (
        <div>
          <h1>Welcome to My App</h1>
          <Suspense fallback={<div>Loading...</div>}>
            {isAdmin ? <AdminPage /> : <UserPage />}
          </Suspense>
        </div>
      );
    }
   
    export default App;
   

3. Higher-Order Components (HOCs): Higher-order components are functions that take a component ad return a new component with additional functionality. They allow you to reuse your code and keep your components clean.

   Let's look at an example

    import {Redirect} from 'react-router-dom'
   
    const withAuth = (Component) => {
        const AuthenticatedComponent = () =>  {
        // this is to check if the user is authenticated
        const isAuthenticated = true;
   
        if (isAuthenticated) {
                // when user is component, it will render this
                  return <Component {...props}/>
            }
        else {
            // this will redirect the user to the login page if not authenticated
                return <Redirect to='/login' />
            }
        }
    }
   

   Now let's apply the Higher Order component we created

    const Profile = () => {
        return (
            <>
                <p>This is my Profile! My name is Coding Pastor</p>
            </>
        )
    }
   
    // import withAuth
    const AuthenticatedApp = withAuth(Dashboard)
   

    const App = () => {
      return (
        <Router>
          <Switch>
            <Route exact path="/" component={Home} />
            <Route path="/dashboard" component={AuthenticatedDashboard} />
            <Route path="/login" component={Login} />
          </Switch>
        </Router>
      );
    };
   

   We wrapped the "Profile" component with the "withAuth" Higher-order component. This will ensure that only authenticated users can access the Profile page. Users that are not authenticated will be redirected to the login page.

4. Context API: Context API is a way to share data between components without passing props down through the entire component. It allows you to create a global state that can be accessed by any component in your application. It is the cure for prop drilling. Sometimes you want a state to be general and accessible throughout your whole application, instead of passing down props and digging through your application, you can use Context API to create a global state. Let's see how we can do that.

   For this example, we will create a context that stores users' data after authentication. Creating a theme context is too common on the internet. Let's do something uncommon.

    import React, { createContext, useState } from 'react';
   
    export const AuthContext = createContext();
   
    const AuthProvider = ({ children }) => {
      const [isAuthenticated, setIsAuthenticated] = useState(false);
      const [userData, setUserData] = useState(null);
   
      const login = (userData) => {
        setIsAuthenticated(true);
        setUserData(userData);
      };
   
      const logout = () => {
        setIsAuthenticated(false);
        setUserData(null);
      };
   
      return (
        <AuthContext.Provider value={{ isAuthenticated, userData, login, logout }}>
          {children}
        </AuthContext.Provider>
      );
    };
   
    export default AuthProvider;
   

    import React from 'react';
    import AuthProvider from './AuthProvider';
    import LoginPage from './LoginPage';
    import ProfilePage from './ProfilePage';
   
    function App() {
      return (
        <AuthProvider>
          <LoginPage />
          <ProfilePage />
        </AuthProvider>
      );
    }
   
    export default App;
   

   To access the user data;

    import React, { useContext } from 'react';
    import { AuthContext } from './AuthProvider';
   
    function ProfilePage() {
      const { userData } = useContext(AuthContext);
   
      return (
        <div>
          <h1>Welcome, {userData.username}!</h1>
          <p>Email: {userData.email}</p>
        </div>
      );
    }
   
    export default ProfilePage;
   

5. React Hooks: This one is very common and used by every React developer., Examples of popular react hooks are the useState hooks, useEffect, useReducer, and more. React hooks provide a simpler and more concise way to manage state and lifecycle methods in your components. We already used the useState hook above. let's see others. We will not be able to touch everything

   1. useEffect Hook: The useEffect hook enables side effects in functional components, such as data fetching, event subscribing, or DOM updates. It takes a function and an optional dependencies array, executing the function after each render based on the dependencies. Use it wisely to prevent performance issues or bugs.

       const [data, setData] = useState(null);
      
       useEffect(() => { 
       const fetchData = async () => { 
       const response = await fetch('https://api.example.com/data'); 
       const result = await response.json(); setData(result); 
       };
      
       fetchData(); }, []);
      
       // from this code above, we are trying to render the data from the fetchData to the page.
      

   2. useReducer Hook: The useReducer hook manages complex state in components, providing more flexibility than useState. It requires a reducer function and initial state and returns an array with the current state and a dispatch function. While powerful, it can be more challenging than useState, especially for React beginners.

       const initialState = { count: 0 };
      
       function reducer(state, action) {
         switch (action.type) {
           case 'increment':
             return { count: state.count + 1 };
           case 'decrement':
             return { count: state.count - 1 };
           default:
             throw new Error();
         }
       }
      
       function Counter() {
         const [state, dispatch] = useReducer(reducer, initialState);
      
         return (
           <>
             Count: {state.count}
             <button onClick={() => dispatch({ type: 'increment' })}>+</button>
             <button onClick={() => dispatch({ type: 'decrement' })}>-</button>
           </>
         );
       }
       // This is a count application with useReducer
      

   3. useRef: The useRef hook is a super helpful tool that lets you create and manage changeable references right inside your functional components. It's often used for directly accessing DOM elements or keeping values that stay the same across renders without making your component re-render. Pretty cool, right?

       import React, { useRef } from 'react';
      
       function TextInput() {
         const inputRef = useRef(null);
      
         const focusInput = () => {
           inputRef.current.focus();
         };
      
         return (
           <div>
             <input ref={inputRef} type="text" />
             <button onClick={focusInput}>Focus Input</button>
           </div>
         );
       }
      
       export default TextInput;
      

   4. useMemo: useMemo is a fantastic React hook that boosts the performance of your app by remembering the outcome of a function, so you don't have to do needless re-calculations. It needs two things: a function that gives you a value, and an array of dependencies. The magic happens when useMemo only re-does the calculation if any dependencies change. This is super handy for complex calculations or when a component keeps rendering often.

       const memoizedResult = useMemo(() => {
         return expensiveCalculationFunction(a, b);
       }, [a, b]);
      

   5. useCallback: useCallback is another react hook that memorizes a callback function, preventing unnecessary re-creating of the function. It takes two arguments: The callback function and an array of dependencies. useCallback will return the memoized version of the callback function, which will only change if one of the dependencies has changed. This is useful for optimizing performance, especially when passing callbacks to child components on a frequently rendered component.

       const memoizedCallback = useCallback(() => {
         doSomethingWith(a, b);
       }, [a, b]);
      

      The use Callback hook is similar to the useMemo hook since they boost the performance of the application. The difference between the two hooks is that while the useMemo hook memoizes the result of a function, useCallback hook memoizes a callback function.

Conclusion

In conclusion, WOW! Utilizing React features like Custom Hooks, Code-Splitting, Higher-Order Components, Context API, and various hooks such as useState, useEffect, useReducer, useRef, useMemo, and useCallback can MASSIVELY enhance your application's performance and code quality! Embrace these AWESOME techniques to not only make your code super efficient but also skyrocket your skills as a React developer! Thank you for reading and HAPPY CODING! 🚀🎉

For those of you who may be reading this without any prior knowledge, allow me to provide some context. A while back, I was browsing through YouTube when I came across a particular post.

I also saw something on the Tailwind CSS website when I wanted to install Tailwind in my React application

I got confused. Why are we not using create-react-app anymore? What is happening? So many questions went through my mind.

What is create-react-app

In case you're not familiar, create-react-app is a React.js build tool and command line interface (CLI), similar to create-next-app or Next.js as some people call it. It's a super handy tool for building front-end web applications. Think of it as a user-friendly command line interface that helps you create React applications with minimal fuss and almost no configuration needed. 😊

Why create-react-app came into existence

Initially, setting up your react project used to be a daunting task for beginners in react.js. from setting installing React-dom, and React to setting up Webpack and Babel was pretty overwhelming. Sometimes one may give up in the process of just trying to install them.

CRA allowed developers to use ES6 syntax with their React applications and eliminated the need for manual configuration, making it easier and faster to get started with building front-end web applications.

Why are developers moving from create-react-app?

1. Speed and Performance: CRA offers pretty much good performance but not until alternatives to setting up your react projects and building your react projects came into existence. Frameworks such as Vite, Next.js, and Astro offer very fast build time and better performance as compared to CRA. With the release of the latest version of Vite, which is extremely fast, Next.js which is not also sleeping in terms of speed, and Astro which is like the flash of them all. Sometimes I wonder how fast we want our websites to load and maybe very soon websites will even load before the user clicks the search button. Lol, I'm just teasing 😅.

2. Control: This is not a major concern, but a concern is still a concern. Some developers, prefer to have more control over what they do and CRA does not offer total control. CRA abstracts away a lot of the configuration that goes into setting up a React project. Even though this is great for beginners who are just starting, some developers with a lot of experience just want to be able to control the configuration of their projects.

Alternatives to CRA

In the world of React Frontend, there are several options. When I say several, I mean many options. Many React frontend frameworks offer better performance and speed.

1. Astro: I put this first cause I have been using this lately to build my frontend applications. It is incredibly fast and it will give you a very good developer experience. One thing I love about Astro is the way it returns the error. It will tell you the error and what is supposed to be there. Not some gibberish that will get you confused.

2. Next.js: Next.js can be considered a full-stack framework as well, but it is built on top of React, offering features like server-side rendering and code splitting. The speed and performance of Next.js are exceptional, making it an excellent choice for developers looking to create fast, efficient, and complex applications.

3. Vite: Vite is a build tool and a development server that is used to build modern web applications. When you combine Vite with React, then we have? I don't know, I will leave it to you to complete it yourself. The latest version of Vite which was released some days ago is the Vite 4.3 version is just so fast. We are not going to be talking about how fast these frameworks may be in another article. However, Vite 4.3 is fast. I tried it out when some hours after it was released and I was shocked. We are going to use an article to check out the speed of these front-end frameworks soon.

4. Remix: Remix is a React framework for building web applications. It is built on top of React and offers features such as server-side rendering, data loading, and routing. Remix focuses on developer experience and performance, delivering a simplified API and quick build times. It serves as an alternative to traditional server-side rendering frameworks such as Next.js.

5. Gatsby: Gatsby is a popular React-based framework for building static websites and web applications. It offers features such as server-side rendering, pre-fetching, and code splitting to improve website performance and user experience. I have not used this framework but hey! if the internet says it's fast then it is fast.

Is CRA Dead?

My answer is no. There are still numerous developers using CRA, and it remains a popular tool for building React applications. Perhaps it is currently struggling, but it isn't dead. If what you want isn't available in CRA, there are better options. Do you need speed? You can try any of the alternatives mentioned previously. Additionally, you should consider that the frontend world is constantly evolving, and it's important to keep up with these changes to avoid being left behind.

We have all encountered errors while building our react application. Errors that will always break our application. And then, when we check our console for the type of error, we see something like this

How do we Deal with Ugly Errors Like this?

1. By Using Error Boundaries

One of the ways to deal with breaking errors in our react application is to use Mr. Error Boundary.

Error Boundaries in React are React Components, that catch errors within our application, log these errors and display a fallback UI. In this scenario, the application does not crash but instead, it renders a new UI where when it encounters an error.

How to use Error Boundaries

Using Error boundaries to take care of our errors is quite easy. First, let us create a React Component and name it ErrorBoundary.tsx.

ErrorBoundary.tsx

import React, { Component } from 'react'

type ErrorProps = {}
export default class ErrorComponent extends Component<Error, {errorPresent: boolean}> {
    constructor(props: any) {
        super(props);
        this.state = { errorPresent: false }

    }

    static getDerivedStateFromError(error) {
        return { errorPresent: true }
    }

    compoenentDidCatch(){

    }

    render() {
        if (this.state.hasError) {
            return( <p>Something went wrong</p>)
        }
        return (<>
            { this.props.children }
        </>)
    }
}

From the code above, we used a class-based approach to write our Error Boundary component instead and not the functional-based approach. Currently, there is no way to write Error Boundaries as a functional component.

1. By using react-error-boundary

   react-error-boundary is a simple reusable React Error Boundary Component.

How to use react-error-boundary

Run npm install react-error-boundary to install the package.

This is a Simple example of how to use react-error-boundary.

import { ErrorBoundary } from "react-error-boundary";

function fallbackRender({ error, resetErrorBoundary }) {
  // Call resetErrorBoundary() to reset the error boundary and retry the render.

  return (
    <div>
      <p>Something went wrong:</p>
      <pre style={{ color: "red" }}>{error.message}</pre>
    </div>
  );
}

<ErrorBoundary
  fallbackRender={fallbackRender}
  onReset={(details) => {
    // Reset the state of your app so the error doesn't happen again
  }}
>
  <MyApplication/>
</ErrorBoundary>;

Conclusion

In conclusion, Error Boundary does not catch errors with the following:

• Asynchronous code

• Event Handlers

• Server-side rendering

To do this, you can use the react-error-boundary package.

Finally, we have been able to learn how to handle errors in React.js like pros.

Change the port from your .env file

You can create a .env file and just add the port number you want to use. Like this

PORT=4000

// .env file
PORT=4000

Once you set it, you can start your react application. React will automatically start the application using the PORT number you specified.

Changing the port from your package.json

You can also change your port number from your package.json file. Let us see how.

Add PORT=3456 to the value of start on MacOS and set PORT=4000 to the value of start on Windows.

On macOS

"scripts": {
    "start": "port=4000 react-scripts start",
 },

On Windows

"scripts": {
    "start": "set port=4000 && react-scripts start",
 },

Changing the PORT number from the Terminal or CMD

Using this method, you are changing the port number using your OS's environmental variable.

// Using cmd
set PORT=4000

// using terminal, or bash
export PORT=4000

// using powershell
$env:PORT=4000

After running this on your terminal or cmd, run npm start to start the project

Using the cross-env package

The cross-env package can also change your port number to a custom port. First, to be able to change our port number using this package, we will have to install, it.

On your terminal or command prompt, run npm install cross-env Once it is installed add cross-env PORT=4000 to the value of start in your package.json

"scripts": {
    "start": "cross-env PORT=4000 react-scripts start",
 },

After doing any of the above methods, your react app should be available on http://localhost:4000

What you will learn

In this tutorial, we are going to cover the basics of Astro, routing in Astro, dynamic routing in Astro, fetching APIs in Astro, and Using Astro with Reactjs

Getting Started With Astro

To build our project, first, we need to create an Astro startup project

npm create astro@latest

After installation, your project structure should look like this

To run our Astro project, we use the command below

npm run dev

Astro ships with built-in support for typescript. We can directly write TypeScript in our Astro component. Astro components end with the extension .astro

Now that we have installed Astro, let's install React. To install React, run;

# Using NPM

npx astro add react

# Using Yarn yarn astro add react

# Using PNPM pnpm astro add react

We need to install the dependencies manually.

npm install @astrojs/react

Most times, the command above installs everything you need but in case you cannot find react, run this

npm install react react-dom

Now, head over to your astro.config.mjs file and paste this

import { defineConfig } from 'astro/config';

import react from '@astrojs/react';

export default defineConfig({

// ...

integrations: [react()],

})

Styling

For our styling, we are going to be using tailwind css.To Set up Tailwind CSS, run the command below

To install automatically,

npx astro add tailwind

The command above should set up the configurations and get you started. If you are facing any issue involving tailwind configuration, click this link

Let's begin the project

Today, we are going to be building a basic movie database, to display a list of movies and also get information about the movies.

First, in your src/ directory, we are going to be creating a few folders. The names of the folders are

1. Component folder. This folder will house our React components.

2. Container. This will house our Astro components.

In the src/ directory, you can also see the pages directory. The pages folder contains the pages of our app. The root page is the index.astro file.

In your container folder, create an Astro component, and name it movie.astro

---
---

<html lang="en">
    <body>
        <div class="">

        </div>  

    </body>
</html>

When you create the file, insert the line of code above. You now be wondering where our JS code will be written. Don't worry, I have your back.

In between the hyphens are where we will insert our code. For example,

---
const name: string = "Coding Pastor"
---

<html>
    <body>
        <div class="">
            <p>My name is {name} </p>
            <p>You see. Life Continues</p>
        </div>  

    </body>
</html>

To get the data for the movies, we are going to be using an API. Head over to https://www.themoviedb.org. Create an account. When your account has been created, go to your settings page to apply to get your API key.

Once you have been given an API key, visit the API documentation. This link should take you to the API we will be using. We won't be able to consume all the APIs, we would only be consuming one which is /movies/popular in this tutorial.

Let's get back to our codebase for now. We want to create a .env file where we will set our API keys and base URI. The .env file should be created in the base directory.

I am going to be using a dummy API_KEY for this tutorial. Please note that the API Key here is incorrect.

// your .env file
BASE_URI=https://api.themoviedb.org/3
API_KEY=123098Iamcodingpastor2345

We have successfully created our .env file. Let's head back to the movie.astro component we created.

---
const url: string = `${import.meta.env.BASEURI}/movies/popular?api_key=${import.meta.env.API_KEY}`
const response = await fetch(url)
const data = await response.json()
console.log(data)
---

From the piece of code above, we want to fetch the API to display the popular movies. If you check your terminal, you should see the data of popular movies being displayed.

When you look at the url too you can see we used import.meta.env instead of process.env . In Astro, when we want to get the environmental variables, we use import.meta.env

To continue, let's create a react component to display our data. We could have fetched everything on the movie.astro component but it is nicer to have a reusable component which will save us more time and fewer lines of code.

In the components directory, create a file and name it GetData.tsx This component will display our data. After creating it, we can add the following line of code.

import React from 'react'

type Props = {
    data: any
}

const GetData = ({ data }: Props) => {
    return (
        <main className='w-full'>
        <div className="px-4">
            {
        data?.results.map((item, index) => {
            return (
            <section key={index}>
            <a href={`${category}/${item.id}`}>
            <div  className='my-4 p-2'>
            <img className="rounded" 
                src={`https://image.tmdb.org/t/p/w500/${item.backdrop_path || 
                        item.profile_path || 
                        item.postal_path}`} alt="images" />

            <p className="border mt-2 border-slate-50 rounded-md hover:bg-    slate-500 w-fit p-1 text-xs">
                    Date: {item.release_date}
            </p>
            <p className='font-semibold text-lg my-2'>
                {item.title || item.original_name || item.name}
            </p>
            </div>
            </a>

            </section>
            )
        })
            }
        </div>
        </main>

    )
}

export default GetData

As we have said, the component above renders our data. Now let's insert this into our movie.astro component.

---
// import GetData
import GetData from '../../components/GetData'

const url: string = `${import.meta.env.BASEURI}/movies/popular?api_key=${import.meta.env.API_KEY}`
const response = await fetch(url)
const data = await response.json()
console.log(data)
---

<html>
    <body>
        <div class="">
           <GetData data={data} />
        </div>  
    </body>
</html>

Up till this point, this should be how our Astro component looks like. We are almost done. Now let's invite the movie.astro page to the index.astro page

In the index.astro page, import the movie.astro page. It can be in the format below

import Movie from '../container/movie.astro

After importing, we insert this page into the body of our page.

---
import Movie from '../container/movie.astro'
---

<html lang="en">
    <head>
        <meta charset="utf-8" />
        <link rel="icon" type="image/svg+xml" href="/favicon.svg" />
        <meta name="viewport" content="width=device-width" />
        <meta name="generator" content={Astro.generator} />
        <title>The Movie DB</title>
        <Navigation />


    </head>
    <body class="bg-slate-800 text-white">


        <section class="">
            <Movie />
        </section>
    </body>
</html>

Now let's see what we have done so far, to run your server use the command

npm run dev

Here we go!!

Conclusion

To recap, in this tutorial we talked about the basics of Astro, routing in Astro, dynamic routing in Astro, fetching APIs in Astro, and Using Astro with Reactjs.

You can check out the full version of the application here and please give it a star on GitHub here. Thank you.

I hope this article has been able to teach you how to start your Astro with React project and ideas. Thank you

It is only a programmer that will understand what it takes and the stress involved in programming.

To understand these jokes, you have to be a programmer, and if you're not don't worry. Laugh and also share them with your friends that are programmers.

I had to search the internet to collect these random programming jokes. So the title should have been Random programming jokes around the internet 😅. Will you get all of them? How great is your sense of humor? Let's see

1. There are 10 types of people in this world. Those who understand binary and those who don't. Okay, did you laugh? or did you not get it? First, this is a binary joke. Binary contains two digits, 0 and 1.

2. The best thing about Boolean is even if you are wrong, you are only off by a bit

3. A son asked his father (a programmer) why the sun rises in the east, and sets in the west. His response? It works, don’t touch it!

4. Copy-and-Paste was programmed by programmers for programmers actually.

5. What is an Algorithm? A Word used by programmers when they don’t want to explain what they did.

6. Software, churches, and cathedrals are much the same — first we build them, then we pray

7. There are two ways to write error-free programs; only the third works.

8. If debugging is the process of removing bugs, then programming must be the process of putting them in.

9. The Best way to debug a code? Delete the code 😅

10. What's the Object-oriented way to become Wealthy? Inheritance 🤣

11. Why did the programmer quit his job? Because he didn't get arrays (a raise)

12. Why do Java Programmers wear glasses? They don't C# 😂 This one got me hard. They don't see sharp

13. A programmer had a problem, he decide to use Java. He now has a ProblemFactory.

14. A story: Once upon a time, 3 Database SQL walked into a NoSQL bar. They walked out. Do you know why? There was no table.

15. The programmer got stuck in a shower because of the instructions on the shampoo state:

    Lather, Rinse, Repeat

16. What did the Java code say to the C code? You’ve got no class. 😅

17. Two bytes meet. The first byte asks, ‘Are you ill?’ The second byte replies, ‘No, just feeling a bit off.

18. ASCII stupid question, get a stupid ANSI. 😂

Others

There are two types of people

if (condition) {
   return statement;
}

if (condition)
{
return statement;
}

which of them are you?

When I wrote this code, only God and I understood what I did. Now only God knows

If debugging is the process of removing bugs, then programming must be the process of putting them in.

Why was the JavaScript developer sad? Because they didn't Node how to Express himself

How do you comfort a JavaScript bug? You console it

Two JavaScript variables are in a bar. "I'm sorry I cannot be with you, your so not my Type.", one says. The other Recasts and they lived happily ever after.

Q: Why did the React class component feel relieved? A: Because it was off the hook

Don't trust JavaScript programmers. All they do is promises but they never callback.

Do you want to know something? this is a javascript joke

Thank you for taking out time to read the article. I wish you fewer bugs in your code and remember if it works don't touch😅. Have a great day ahead.

Solidity is an object-oriented programming language for writing smart contracts. It is a high-level language for implementing smart contracts. It is the primary language for writing smart contracts in the Ethereum Blockchain.

What is a Smart Contract?

A smart contract is a program or a piece of code that governs and controls actions within the blockchain.

To practice some Solidity basics, we are going to use the Remix IDE. Remix is an online open-source IDE that allows us to write and deploy our smart contracts.

If you are a beginner and this is your first time trying the solidity language, don't worry this guide is also for you. As long as you have programming knowledge you are good to go. Even if you don't, you are also good to go.

// an example of a simple smart contract
pragma solidity 0.8.11;

contract MyContract {
  // Set Global public variables (make getters with "public")
  uint8 public storedNumber;

  // let's create a function to change numbers by anyone. Must not be the same number
  // If it is, it will fail with the message "They are the same number"

  function changeNumber(uint8 newNumber) public {
    require(storedNumber != newNumber, "They are the same number")
       storedNumber = newNumber 
  }

  // This is how to return a public variable. This is already set with public
  // however for non public variables, this is how we create them
  function getCurrentNumber() public pure returns(uint8) {
    return storedNumber;
  }
}

This is what a smart contract looks like.

Now let's get some fundamentals.

Solidity Data Types

Data types are classifications or types which tell the computer how we want to use the data.

1. Boolean

The bool data type is used to represent situations that have binary results, such as 1 or 0, true or false. The 0 is false and the 1 is true.

The Solidity language supports both logical and comparison operators.

Logical

! Logical Negation

&& And

|| OR

Comparison == equality

!= inequality

// an example of the bool data type in solidity
pragma solidity 0.8.11;

contract MyBool {
      bool public isSet = True;
      bool public isPresent = False;
}

2. Bitwise Operators

& And

| OR

^ XOR

~ Bitwise negation

<< Left Shift

>> Right Shift

3. Arithmetic Operators

+ Addition

- Subtraction

* Multiplication

/ Division

% Modulo

Value Types in Solidity

1. Addresses

Addresses in solidity hold a 20-byte value which represents the size of an Ethereum address. An address is a unique public key that points to a wallet where assets can be stored.

pragma solidity ^0.8.1;

contract FirstProgram {
        address public walletAddress = "0x2Dc85851940eC853f63587c45751126E1877d8C0";


}

2. Enums

enums or enumerable in solidity are used to create user-defined data types. It restricts the variable to only one of the pre-defined values.

Enums allow the contract more readable, and maintainable. it also reduces the errors in the contract.

pragma solidity ^0.8.1;

contract MyFirst {

// let's create an enum
enum Switch  {
ON,
OFF
};

// create a variable of type enum
Switch switch;

//create a function to turn on the light switch
function onSwitch() public{
    switch =  Switch.ON;
}

// create a function to turn off the light switch
function offSwitch() public {
      switch = Switch.OFF;
}

// lastly we create a function that gets the value of the Switch
function switchReturn() public view returns(Switch) {
// finally let's return the value of the Switch
  return Switch;
}
}

Reference Types in Solidity

4. Arrays

An array is a collection of elements of the same data type which can be identified using their location called index.

An array can either be dynamic or fixed.

// Creating arrays in solidity
address[] addresses
uint256[] myArray

// Add to array
function add() internal {
// adding value to an array
  myArray.push(123); 
}

Example of Dynamic array and fixed array

uint256[] dynamicArrays;

uint256[5] fixedArrays;

5. Struct

Struct allows us to create more complicated data types and define our own type in form of structures.

struct people {
  string name; 
  uint256 favoriteColor;
  uint256 age;

}

6. Mapping

Mapping is similar to Dictionary or Hash tables in other languages. It accepts a key type and value type pair.

Mapping Syntax

mapping(key_type => value_type) mappingName;

struct people {
  string name; 
  uint256 favoriteColor;
  uint256 age;

}

mapping(address => people) bio;
address[] public people_bio;

Conclusion

In this article, we discussed Solidity and its data types, value types, and reference types. We also explained what smart contracts are and how they are connected to solidity.

First, let's think together about what SSH may mean, Sterilized server host 😏 or Service Saving Hosting 😏. What was your thought, share in the comments section.

Okay, so enough thinking, let us dive right in. SSH stands for Secure Shell Protocol. Yes, that's what it stands for. Now that you know, do you understand what that word means? What is getting secured? and where is the shell?

SSH is a remote administration protocol, that allows users i.e. you and me, to access, control, and modify their remote servers over the internet. This is a lot to take in. So many words. Now let's break it down. Take this as an example, Mr. A is a Software engineer at Hashnode. On a weekend, Mr. A was contacted from his place of work, Hashnode that something is wrong, some deprecated packages needs to be uninstalled and we have to update some other packages too. Mr. A, who has probably traveled and is far away from his workplace has been told to resolve the issue. At this point, you may think he will have to wait till Monday when he gets to his office or someone else close to the office who can handle should do it.

This is where our brother, SSH comes in. SSH gives you access or modification to servers remotely. So, Mr. A from his relaxation zone, resolved the issue using SSH protocol. Please don't ask me what the issue was because I don't know it 😅. When you see Mr. A, ask him.

You must be thinking now, I'm going to know this, it is going to make you look cool 😏. Yeah sure, but just be prepared because we are just getting started 😅.

How Does SSH Work?

It is easy to use SSH on Mac or Linux, but you know on Windows, it's not hard but also not easy. Things are not always easy for us windows users.

To connect to a server using SSH, we just need a command with 3 easy parts

ssh {user}@{host}

Are you confused again, Don't worry let's continue the trip. The user from the command refers to the account you want to access, while the host is the server or computer you want to connect to. Check this out. It is just a demo. If you run it won't work

ssh root@111.22.333.444.55

Now you see it.

The SSH key tells your computer that you need a secure shell session with the other computer. Just so you know, for the time of the session, all the commands you run on your terminal or CMD is encrypted.

Techniques used in SSH Encryption

As you now know that SSH uses encryption to ensure a secure sending of information between the Host computer and your computer. There are three techniques used by SSH for encryption:

1. Symmetrical Encryption
2. Asymmetrical Encryption
3. Hashing

1. Symmetrical Encryption

First, encryption is a way of converting data into code to prevent unauthorized access.

Symmetric encryption uses just a single key to send information from the client computer to the host computer. If I wanted to send a message to another computer, using the symmetrical encryption technique, I will have a key that encrypts the word. And inasmuch as the other computer has that same key I have, he can decrypt the word. That's it. It's just so Symmetrical.

2. Asymmetric Encryption

Asymmetrical encryption unlike its brother, symmetrical uses two separate keys to encrypt and decrypt a message. It may get confusing from here and it may not. These two keys are known as Public and Private keys. Combining them they both form a thing called, public-private key pair. Together, they're almost unbreakable.

A message sent using the sender's public key can only be decrypted if the receiver possesses the sender's private key. This makes the encryption more complicated.

SSH does not entirely use Asymmetric encryption. It is only used during key exchange algorithms in symmetric. During the symmetric key exchange, we need a way to generate the symmetric key without it becoming public. To get the symmetric key, we use a method called the Diffie Hellman Key Exchange.

3. Hashing

Hashing is another form of cryptography used in secure shell connections. One-way hash functions differ from the two stated techniques of encryption. The symmetric and asymmetric encryption techniques are not meant to decrypt anything. They simply generate a unique value for a fixed length for each input.

It is easy to generate a cryptographic hash from input, but impossible to generate input from the hash. Hope you are not confused? This means that if a client should have the correct input, they can generate the cryptographic hash and compare if it is correct.

To verify the authenticity of a message, SSH uses Hashes. This is done using Hash-Based Message Authentication HMX. Using a hash function, each message transmitted must contain a MAC which is a hash that is generated from a symmetric key. MAC stands for Message authentication code.

Passwords or SSH - Which is better?

First, it is harder to hack SSH keys which makes it more secure. SSH keys can be very long, making them more complex and difficult to hack.

First, to use the useState Hook, you import it from 'react'

import { useState } from 'react

The useState function takes two arguments; an initial state and it returns an array of two entries (the current state and the function that updates the state).

 const [count, setCount] = useState(0);

import {useState} from 'react'

function NumberChange() {
 const [count, setCount] = useState(0);
}

from the code above, the count is the current state while the setCount function is used to update our state.

We then set our initial state to zero useState(0)

Let us look at an example. We will change the number from its initial value of zero (0) to another value.

import { useState } from "react";

function NumberChange() {
  const [count, setCount] = useState(0);

  return <h1>The First Number is  {count}</h1>
}

Now, let's update the state

import { useState } from 'react'

function NumberChange() {
 const[count, setCount] = useState(0);

return(
    <div>
             <h1>The First Number is  {count}</h1>
             <button onClick = {() => 
                    setCount(1);
                }></button>
    </div>
)

}

Web 3.0 has come into existence to remove the middle-men in interactions. In Web 2, for an interaction to be performed, there would be a middle-man, an intermediary. They extract interactions that are just between two parties. We appreciate these platforms because, without them, there won’t be a way to interact with our other party. Web 3 came into existence to end the intermediary.

With cryptocurrencies like Bitcoin and Ethereum, we can now have a peer-to-peer interaction without a middle-man and intermediary. With bitcoin, we can perform financial interactions without intermediaries.

Julia, sounds familiar, right? It is an open-source high-level, dynamic programming language. It is a general multi-purpose language that can be used in many areas of application. It was written in C++ as many other languages too. It was developed in 2012 by Jeff Bezanson and his team.

I started with the Julia programming language 2020, during the corona outbreak. Now, I had just started my Data Science course and I got to know this language whose name sounded odd, Julia. At first, I did not know it was a language, I thought it was a python framework. Afterward, I learned it, and Jeez found out it is a language worth trying.

function f()
           println("I love Julia")
       end

Julia is a fast scripting language that has various applications.

Applications of Julia

1. Data Science
2. Machine Learning
3. Web Development
4. Data Visualization

Data Science

This should probably have rung a bell in you. Data Science is an area of study that deals with chunks of data being processed. From the two words, data and science. Science on its own is the systematic study of the behavior of a particular thing. So in combination with the word Data, it is the study of the behavior of Data. Processing and analyzing these data is what Data Science to predict the outcome of an event, find an unseen pattern, gain more information and make decisions is all about. For all this, we use modern tools and techniques which will be listed below.

Techniques used in Data Science

1. Regression
2. Clustering
3. Decision Trees
4. Random Forests
5. Visualization
6. Probability and Statistics

Machine Learning

This should sound familiar too. If you haven't heard this before, then this confirms you are an alien. So, if you have not heard this word before, in simple terms Machine Learning means Machine Learning(i.e a machine that learns). Now, since we all know what Machine learning is all about, let's drive.

Machine learning is the study of computer algorithms that can improve automatically through experience and by the use of data. It deals with you providing a system with so much data that it will learn from. This will enable the system to predict future occurrences and events.

The Julia programming language uses the MLJ.jl package to provide a unified interface to common machine learning algorithms, which include generalized linear models, decision trees, and clustering. You are now almost confused with what the text in italic means, right? Do not worry, I am with you in this. It is just a package in Julia for Machine learning that contains several modules.

Web Development

This is the most common of them all. You have surely heard of Web development and you know what it means. The Julia programming language uses Genie.jl, a full-stack web framework that provides a streamlined and efficient workflow for developing modern web applications.

The Julia programming language can also be used to write web UI or native UIs, and also for scripting or automation.

<a href='http://example.com'>What does Href mean?</>

From the code above, the href is an attribute within an anchor tag <a></a>, which is used to identify sections within a document or to create a link to a page.
