Velocity is a jQuery plugin that re-implements $.animate() to produce significantly greater performance (making Velocity also faster than CSS animations) while including several new features to improve animation workflow.

Velocity outperforms jQuery at all levels of stress, Transit beginning at medium levels of stress, and GSAP beginning at high levels of stress. At minimum, Velocity is always on par with other engines. In just 7Kb, Velocity includes all of $.animate()’s features while also packing in color animation, transforms, loops, easings, class animation, and scrolling. Velocity is the best of jQuery, jQuery UI, and CSS transitions combined.
