Package Exports
- ease-component
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ease-component) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

var requestAnimationFrame = require('raf');
var canvas = document.querySelector('canvas');
var ctx = canvas.getContext('2d');
var stop = false;
function animate() {

}
var startx = 20;
var x = startx;
var destx = 300;
var y = 400 / 2;
var duration = 1000;
var start = Date.now();
var end = start + duration;
function draw() {
var now = Date.now();
if (now - start >= duration) stop = true;
var p = (now - start) / duration;
val = ease.inOutBounce(p);
x = startx + (destx - startx) * val;
canvas.width = canvas.width;
ctx.fillStyle = 'red';
ctx.arc(x, y, 10, 0, Math.PI * 2, false);
ctx.fill();
}
