tween.js is a JavaScript/TypeScript tweening engine for easy animations, incorporating optimized Robert Penner's easing equations. It tweens properties of any object over time and integrates into any animation loop you provide.

Use cases

  • animate dom element properties with easing
  • tween object properties over time in javascript
  • smooth easing animations for web ui
  • create tweened animations for canvas or webgl
  • interpolate numeric values with easing functions
  • add animation to a three.js scene

When to choose

  • you want a small, focused tweening library that only interpolates object properties
  • you need reusable easing functions or custom easing curves
  • you want to plug tweens into your own animation loop
  • you need a battle-tested library with TypeScript support

When to avoid

  • you need CSS unit handling or color interpolation out of the box
  • you want a full-featured animation framework with built-in animation loops and timelines
  • you need keyframe-based CSS animation tooling
