AJAX stands for Asynchronous JavaScript And Xml. The technique allows for data retrieval in a portion of the web page while none of the other elements need to be reloaded. AJAX lets you do more than one thing at a time on a web page.
In this example, you can watch the Evian babies dance while loading different web development cheat sheets. Without AJAX, the movie would have to reload every time you selected a different sheet.
