Asynchronous JavaScript and XML – AJAX

Asynchronous JavaScript and XML, or AJAX, is a method used in web development to update parts of a web page without needing to reload the entire page. It allows a browser to communicate with a server behind the scenes, making web applications faster and more interactive.

AJAX exchanges data with the server using a combination of web technologies such as JavaScript, the XMLHttpRequest object, and formats like JSON or XML. Instead of refreshing an entire webpage, AJAX fetches small amounts of data and updates only specific elements. This approach improves the user experience by creating more responsive and seamless applications. Most modern web apps rely on AJAX or similar techniques to deliver dynamic content.
