Jank Busters: Building Performant Web Apps

In my post yesterday on Chrome Developer Tools – No More Firebug I mentioned that Developer Tools can be used to remove jank from web pages. Jank is a difficult term to describe in words but essentially it’s when a web page doesn’t respond smoothly during scrolling or an animation event. Jank is usually caused by a paint event taking too load or a JavaScript function not being coded with browser performance in mind.

Check out the video and you can learn how to use Developer Tools to trace down janky web pages. Once you’ve got your head around jank then you can always lend a helping hand to WordPress core.
