AJAX is an acronym for Asynchronous JavaScript and XML. AJAX is a technique used to make web pages more interactive by using JavaScript.
Web applications are a lot of fun to build. Of course, some websites although fun to build, can be rather slow and tedious. Even the fastest of web pages can be rather slow and gives you time to go for a coffee break. We all know that the dreaded hourglass can leave us all in awe and can even push us to go onto other websites that have a faster speeds.
AJAX is the way of programming that gets rid of the hourglass. With AJAX driven application, you click onto something, and there is very little wait time. The page can simply display what you are asking for very quickly and even in real time, which creates a continuous feel to any website.
