femtoTween's goal is to provide just enough tweening functionality to cover basic use cases. Through this primary goal, it should also be one of the smallest tweening libraries (less than 1k un-minified even).

yarn add femtotween
import { tween } from 'femtotween'
Minimal API can be grok'd in seconds

Supports a done callback - especially useful for Vue.js transitions via JS hooks
