Understanding JSX: Writing HTML in JavaScript

JSX, or JavaScript XML, is a syntax extension for React.js that allows you to write HTML-like code within JavaScript. This makes building user interfaces more intuitive and visually straightforward.

What is JSX?

JSX looks like HTML but is actually JavaScript. For example:

const element = <h1>Hello, world!</h1>;

This JSX code is transformed into JavaScript by a preprocessor like Babel:

const element = React.createElement('h1', null, 'Hello, world!');

Why Use JSX?

1. Readability: JSX closely resembles HTML, making your code easier to understand.
2. Dynamic Content: You can embed JavaScript expressions in JSX using curly braces {}

JSX simplifies UI development by combining HTML-like syntax with JavaScript’s power, making React code more intuitive and maintainable.
