JSX is a syntax extension for JavaScript that is used with React to create and describe the structure of UI components. It is a syntax that resembles HTML, but it is actually a language that is compiled into JavaScript.

JSX allows you to write your React components using a familiar, HTML-like syntax, which makes it easier to understand and write. Here is a simple example of a React component written using JSX:

import React from 'react';

class MyComponent extends React.Component {
  render() {
    return (
      <div>
        <h1>Hello, World!</h1>
        <p>This is a paragraph.</p>
      </div>
    );
  }
}

In this example, the render() method of the MyComponent class returns a <div> element containing an <h1> heading and a <p> paragraph. This JSX code looks very similar to HTML, but it is actually compiled to JavaScript by the React library.

In JSX, you can use JavaScript expressions inside curly braces {}, and this includes using if statements to control the rendering of elements.

Here is an example of an if statement in JSX:

import React from 'react';

class MyComponent extends React.Component {
  render() {
    const isLoggedIn = true;

    return (
      <div>
        {isLoggedIn && <p>Welcome back!</p>}
      </div>
    );
  }
}
