AJAX (Asynchronous JavaScript and XML) is a technique used in WordPress to update content on a page without requiring a full page reload.
AJAX allows WordPress to dynamically update content without disrupting the user experience. This can be used for various features such as loading more posts on a blog page, adding items to a shopping cart, and updating comments in real-time.
AJAX works by sending an HTTP request to the server and receiving a response in the form of JSON or XML data, which can then be used to update the page content.
