JSX files are not directly compatible with all web browsers. JSX is a syntax extension used by React to write HTML-like code in JavaScript. However, browsers do not understand JSX code natively.

  To use JSX in a web browser, React applications need to be transpiled into regular JavaScript using a tool like Babel. This transpilation process converts JSX syntax into valid JavaScript that can be understood by browsers. The transpiled JavaScript file can then be included in the web page, allowing React components written in JSX to be rendered on the browser.

  It's important to note that modern web browsers, such as Chrome, Firefox, Safari, and Edge, have good support for JavaScript and can handle transpiled JSX code without any issues. However, older browsers may not have complete support for the latest JavaScript features and may require additional configurations or polyfills for JSX to work properly.

  In summary, while JSX itself is not directly compatible with all web browsers, React applications that use JSX can be transpiled into regular JavaScript to ensure compatibility with a wide range of browsers.
