React is a JavaScript library for building user interfaces, especially single-page applications. It is maintained by Facebook and a community of individual developers and companies.

Key Features

  • Declarative: React makes it painless to create interactive UIs. Declare how your app should look, and React will efficiently update and render just the right components.
  • Component-Based: Build reusable UI components that you can compose into complex UIs.
  • Learn Once, Write Anywhere: React can be used with other libraries or frameworks in your app.

Getting Started

To get started with React, you can use Create React App, a tool that sets up the initial structure for your application.

npx create-react-app my-app
cd my-app
npm start

Example

Here's a simple example of a React component:

import React from 'react';

function App() {
  return (
    <div>
      <h1>Hello, world!</h1>
    </div>
  );
}

export default App;
