Velocity.js – Accelerated JavaScript animation

Velocity is a jQuery plugin that re-implements $.animate() to produce significantly greater performance (making Velocity also faster than CSS animation libraries) while including new features to improve animation workflow. Velocity includes all of $.animate()’s features while packing in color animation, transforms, loops, easings, sequences, and scrolling. Velocity is the best of jQuery, jQuery UI, and CSS transitions combined.

Just swap out .animate() with .velocity():

$("div").velocity({ left: 100 }, 1000);
$("div").velocity({ left: 100 }, 1000, "swing");
$("div").velocity({ left: 100 }, "swing");
