What Is Ajax?

In this video we take a look at how Twitter uses AJAX to refresh their timeline and spend some time talking about the javascript XMLHttpRequest object. Then we add an AJAX refresh to an application which pulls images from instagram. Finally when we hit a snag due to the browser same-origin policy we explore JSONP as an alternative to XHR.
