AJAX (Asynchronous JavaScript and XML)

AJAX (Asynchronous JavaScript and XML) is a web technology that allows a webpage to communicate with a server and update parts of its content without reloading the entire page. It enables smoother, faster interactions by sending and receiving data behind the scenes, often using formats like JSON instead of XML. For example, when you check notifications or send a message without leaving the page, AJAX makes this seamless experience possible. It improves user experience by making web applications more dynamic and responsive, closely mimicking the behavior of desktop software.
