JSX (JavaScript XML) is a syntax extension for JavaScript that allows you to write HTML elements within JavaScript code. JSX is how React creates a page's DOM.

Example of JSX:

          {`import React from "react";
          
          function App() {
            return (
              <div>
                <h1>Hello, World!</h1>
                <p>This is a JSX example.</p>
              </div>
            );
          }
          
          export default App;`}
