React is a powerful JavaScript library for building user interfaces. Here's a quick guide to get you started!

📌 1. What is React?

React allows developers to create reusable UI components and manage the state of web applications efficiently.

It’s widely used for single-page applications and is part of the React Ecosystem (🔗 /en/technology/react-ecosystem).

🧩 4. Component-Based Development

• Functional components vs. Class components.

🚀 5. Building Your First App

1. Create a component:

   function HelloWorld() {  
     return <h1>Hello, React!</h1>;  
   }  
   

2. Render it in the DOM:

   ReactDOM.createRoot(document.getElementById('root')).render(<HelloWorld />);
