What is JSX and how does it work?

JSX (JavaScript XML) is a syntax extension for JavaScript that allows you to write HTML-like code in JavaScript.

It gets transformed into regular JavaScript function calls by a transpiler like Babel.

JSX makes React components more readable and allows you to write HTML-like syntax directly in your JavaScript code.

It's not required to use React, but it's the recommended approach.

// JSX Example const element = <h1>Hello, World!</h1>;

// Transpiled to: const element = React.createElement('h1', null, 'Hello, World!');
