Animation Delay with rAF

rAFAnimate.js

function animate (callback, time, oldTime) {
  var oldTime = oldTime || new Date().getTime();
  var now = new Date();
  if (new Date(oldTime + time) < now) {
    callback();
    oldTime = now.getTime();
  }
  requestAnimationFrame(function() { animate(callback, time, oldTime); });
}

//useage:
//animate(animateMyThing, 1000);

To use this you probably also need the rAF polyfill: http://www.paulirish.com/2011/requestanimationframe-for-smart-animating/

...or maybe you don't. Support is pretty good now: http://caniuse.com/#search=requestanimation
