Asynchronous JavaScript and XML (AJAX)

AJAX, which stands for Asynchronous JavaScript and XML, is a technique used in web development that allows websites to update content dynamically without needing to reload the entire page. It works by sending requests to servers in the background while you continue browsing, and then updating only specific parts of the webpage based on the response. This creates a faster, smoother experience, similar to how apps load data seamlessly without interruptions. Though XML was originally used, today AJAX often uses formats like JSON. Overall, AJAX improves interactivity and responsiveness of websites.
