What is AJAX?

Published on: May 6, 2017

Welcome to the 46th Easy JavaScript tutorial, part of EasyProgramming.net. Do you know what is AJAX? Whether you know off the top of your head what it is or isn't, you've probably interacted with it. For example, if you post a comment in the description below, the page will automatically post your comment without updating. That's AJAX. 

In this video, I explain to you what AJAX is and give you a brief intro to some examples before we cover them in tutorial 47 and 48. 

AJAX is extremely useful in increasing the quality of your users experience, also known as UX. AJAX allows you to run new code on your site without the page having to refresh. You've probably submitted forms in the past where after you press enter, it just submits, no page refreshes, no reloading of the images, nothing. It just happens! And it's easy and seamless. 

No Fiddle this time! Enjoy the simple PowerPoint presentation and a view into what we've done in Brackets. 

jQuery makes AJAX a little simpler because it makes the syntax a little simpler. Stay tuned for the jQuery tutorial series coming up after I'm done with JavaScript!
