    Shifty : A teeny tiny tweening engine in JavaScript

    Shifty is a tweening engine for JavaScript. It is a lightweight library meant to be encapsulated by higher level tools. At its core, Shifty provides:

    • Interpolation of Numbers over time (tweening)
    • Playback control of an individual tween
    • Extensibility hooks for key points in the tweening process

    This is useful because it is the least amount of functionality needed to build customizable animations. Shifty is optimized to run many times a second with minimal processing and memory overhead, which is necessary to achieve smooth animations.
