AJAX in web applications

AJAX, or Asynchronous JavaScript and XML, is a technology used in web applications to create a smoother user experience. It allows web pages to send and receive data from a server in the background without needing to reload the entire page. This means you can see new information, like chat messages or notifications, almost instantly. For example, when you scroll through social media and new content automatically appears, that's often AJAX at work, making your online interactions faster and more fluid. Overall, AJAX helps make websites more dynamic and responsive.
