Velocity.js is an animation engine that incorporates the exact same syntax as Jquery’s .animate. Just implement Velocity.js into your project, and watch the increase in animation performance on your already existing Jquery animations. Take things a step further and see what Velocity can do. The Velocity.js features color animation, transforms, loops, easings, SVG support, and scrolling. Once you try it, you’ll agree that neither Jquery animations, nor CSS transitions can compare to the speed and flexibility of Velocity.js.
Velocity.js is made by Julian Shapiro, and is a widely popular library on the dev circuit. It’s used by Tumblr, Orbitz, just to name a few.
