AJAX Tutorial

AJAX = Asynchronous JavaScript and XML (Asynchronous JavaScript and XML).

AJAX is not a new programming language, but a new method of using existing standards.

The biggest advantage of AJAX is that it can exchange data with the server and update parts of a web page without reloading the entire page.

AJAX does not require any browser plugins, but it does require the user to allow JavaScript to execute in the browser.

XMLHttpRequest is just one way to implement AJAX.
