JEasing is a simple library that implements Robert Penner's easing equations. These equations are encapsulated in the module pattern. JEasing is written in pure Javascript. It has no dependency.
JEasing runs both in the browser an on Node.js.
We provide a version without a link to the parent library (without this). Thus, you can include it in your own library.
This README isn't a tutorial on Easing equations. If you need to understand what are the Easing equations, you can refer here.
const JEasing = require('jeasing');
// t: current time, b: beginning value, c: change in value, d: duration
const val = JEasing.linear(t, b, c, d);
var val = JEasing.linear(t, b, c, d);
