rafscroll – chain your scroll events to requestAnimationFrame

new rafscroll(function() {
  // Do your thing here.
});

Your monitor refreshes at 60 frames per second (fps). Scroll events, on the other hand, do not. Chaining your scroll events to a requestAnimationFrame ensures that your transitions and animations will refresh each time the monitor refreshes, rather than each time a scroll event is fired.
