Treehouse is getting ready to launch a brand new course, Ajax Basics. In this short video Treehouse teacher, Dave McFarland, explains what it is used for.

What Is Ajax?

It’s a way to use JavaScript to talk to a web server, get back a response and update a web page without the visitor leaving the current page. Dave shows how sites like Google, Twitter and Reddit use Ajax to make their sites faster and more responsive.

Dave’s course will be released at the end of June.
