Learn React
React is a JavaScript library for building user interfaces.
React is used to build single-page applications.
React allows us to create reusable UI components.
Our "Show React" tool makes it easy to demonstrate React. It shows both the code and the result.
Example
import { createRoot } from 'react-dom/client';
function Hello() {
return ( <h1>Hello World!</h1> );
}
createRoot(document.getElementById('root')).render( <Hello /> );
