How to create a Hello Word Web Page in React JS?

Creating a ?Hello, World!? page in React.js is a great way to get started. Let?s walk through the process step by step:

Setting Up Your Environment:

• First, ensure you have Node.js and npm (Node Package Manager) installed on your system.
• If not, download and install them from the official website: Node.js.

Create a New React App:

• Open your terminal or command prompt.
• Run the following command to create a new React app using Create React App (CRA):

npx create-react-app hello-world

• Replace ?hello-world? with your preferred project name.

Navigate to Your Project Directory:

• Change into the newly created project directory:

cd hello-world

Edit the src/App.js File:

• Open the src/App.js file in your favorite code editor.
• Replace the existing content with the following:

import React from 'react';



function App() {

  return (

    <div className="App">

      <h1>Hello, World!</h1>

    </div>

  );

}



export default App;

Run Your React App:

• In the terminal, run:

npm start

• This will start your development server, and your app will open in your default web browser.
• You?ll see the ?Hello, World!? message displayed on the page.

Understanding the Code:

• The App component is a functional component that returns JSX (JavaScript XML).
• JSX allows you to write HTML-like code within your JavaScript files.
• The <h1> tag inside the App component displays the ?Hello, World!? message.

Customization:

• Feel free to customize your app further by adding more components, styling, or additional content.

Congratulations! You?ve created your first React app!

Remember that React components are the building blocks of your app. You can create more components, nest them, and build complex applications. Happy coding! ??
