Animations made with requestAnimationFrame appear less jumpy and stuttery than those using setTimeout or jQuery.animate by ensuring that animation frames are generated at the most optimal times according to the CPU load, what the browser is doing, what the graphics card is doing, etc. Recently, I researched a bit about how it works, how different browsers behave with it, and how well browsers are at animating both Canvas and SVG. This article will be a brain dump of all I have learned so far. Some of what I discovered may surprise you.
