Write Hello World in React.JS with free codes

Here we are going to Animate the Hello World in React.JS. Which teaches you a basic concepts about React.JS how it’s work how we use that concepts in our code.

1. Set Up Your React Environment

If you haven’t already set up a React environment, you can use Create React App to quickly get started.

Run the following commands in your terminal:

npx create-react-app hello-world
cd hello-world
npm start

This will create a new React project and start a development server.

2. Modify App.js

Once the environment is set up, you can modify the App.js file to display “Hello World”. Here’s how you do it:

// src/App.js
import React from 'react';

function App() {
  return (
    <div className="App">
      <h1>Hello World</h1>
    </div>
  );
}

export default App;

3. Run the Application

After saving the changes, your React app should automatically reload, and you should see “Hello World” displayed on the screen.

If the development server isn’t running, you can start it by running:

npm start

This will open your React app in the browser, displaying the “Hello World” message.
