AJAX Quick Start
The great advantage AJAX can bring to a web application is that it improves the responsiveness
of the application. Responsiveness is a term we use when speaking about how fast an application
responds to a user??™s request. In the world of web development, this includes the time it
takes for a web site (the server) to respond to a clicked link or to update a page with new data.
The term AJAX was coined by Jesse James Garrett (http://www.jjg.net/about/) in 2005 as
an acronym for Asynchronous JavaScript and XML. What??™s in a name? If you say ???not much,???
we agree, at least in this case. AJAX is a programming technique that uses JavaScript on the client
side to make background server calls and retrieve additional data as needed, updating certain
portions of the web page without causing full page reloads.
