React JSX

JSX is a syntax extension for JavaScript that allows you to write HTML-like code in your JavaScript files. It was designed to make it easier to write and maintain large applications built with React, a JavaScript library for building user interfaces.

JSX looks similar to HTML, but it has a few important differences. For example, in JSX, you can use JavaScript expressions inside of curly braces ‘{}‘. This allows you to use variables and functions inside of your JSX code.

Here’s an example of JSX syntax:

import React from 'react';

function MyComponent() {
  const name = 'John';
  return <h1>Hello, {name}!</h1>;
}

export default MyComponent;

This code will render an ‘h1‘ element with the text “Hello, John!”.

JSX syntax is not valid JavaScript, so it needs to be transpiled (converted) into regular JavaScript before it can be run in a browser. This is usually done using a tool like Babel.
