AJAX functionality

Question

What does AJAX actually do?

Re: AJAX functionality

AJAX is an acronym for Asynchronous JavaScript and XML. AJAX can be read "empowered JavaScript", because it essentially offers a technique for client-side JavaScript to make background server calls and retrieve additional data as needed, updating certain portions of the page without causing full page reloads. AJAX comes with the solution to balance the load between the client and the server by allowing them to communicate in the background while the user is working on the page.
