React is one of the most popular JavaScript libraries for building fast, interactive, and reusable user interfaces. Whether you’re a beginner or transitioning from basic JavaScript, React makes creating web apps simple and efficient. In this mini tutorial, you’ll learn how to set up and build your first React app in just minutes.

First, install Node.js and use the command:

npx create-react-app my-appcd my-appnpm start

This creates a ready-to-use project and opens it in your browser. Inside the src folder, you’ll find App.js — your main component. Modify it to display your own text:

function App() {  return <h1>Hello, React World!</h1>;}export default App;

Save the file, and your browser instantly updates. React’s component-based architecture allows you to break your UI into small, reusable pieces, making development faster and more organized.

With React’s virtual DOM and one-way data flow, your apps remain fast, scalable, and easy to maintain. Once you’ve built this first app, you can experiment with props, state, and hooks to create dynamic features.

Start small, practice daily, and React will quickly become your go-to tool for modern web development.v
