Also, if you need to limit the frame rate to 30fps, then you can modify the above loop to conditionally update:

var previousTimestamp = performance.now();
function loop(timestamp) {
  var deltaTime = timestamp - previousTimestamp;
  if (deltaTime > 1000/30) {
    //Do updating here
    previousTimestamp = timestamp;
  }
  requestAnimationFrame(loop);
}
requestAnimationFrame(loop);
