Getting Started with React

React is a JavaScript library for building user interfaces. We can start React by building a simple app.To get started, first of all, make sure to have the node installed in your system.

create-react-app

npx create-react-app app-name

This syntax will set up everything we need for the react app.

Run the App

cd app-name
npm start

The cd app-name will take us to the project directory and npm start runs that react app.

The project will start on localhost:3000 and will look like this:

Modify App.js

let's modify App.js to print a simple "Hello React" text.

import './App.css';

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

export default App;

Here, we created a simple react app just to get started with react. You can learn more on react on our site ahead.
