AJAX

Asynchronous JavaScript and XML

A technique used to build dynamic and responsive web applications that can update parts of a page without requiring a full page reload. In traditional web development, when a user interacts with a website, the browser sends a request to the server, which responds by sending a full HTML page. This process can be slow and cumbersome, especially when only a small portion of the page needs to be updated.

With AJAX, JavaScript is used to send asynchronous requests to the server in the background, allowing the page to continue functioning while waiting for a response. The server responds with data in a structured format, such as XML or JSON, which the JavaScript can then use to update the page without requiring a full reload.

AJAX is widely used in modern web development to create dynamic and responsive user interfaces, and it has been a key component in the rise of web applications and web services.
