JSX is a syntax extension in React that makes writing UI code simpler and more intuitive. It looks like HTML but is written within JavaScript, allowing you to combine your UI structure and logic seamlessly.

Key Advantages:

• Simplified Syntax:

JSX allows you to write HTML-like code directly in JavaScript, making your code easier to read and understand.

• Better Developer Experience:

With JSX, you can quickly spot and fix errors, making debugging easier.

• Keeps Code Organized:

JSX keeps your JavaScript logic and UI structure together in one place, reducing the need to jump between files.

Example: JSX vs JavaScript + HTML

• JavaScript + HTML:

const heading = document.createElement('h1');heading.textContent = 'Hello, world!';document.getElementById('root').appendChild(heading);

• JSX in React:

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

With JSX, you write less code and achieve the same result more efficiently.
