Quick Answer
Heavy animations efficiently: prefer CSS animations over jQuery .animate() for GPU-accelerated transform/opacity. Limit the number of simultaneously animating elements. Use will-change: transform on elements about to animate. Use .stop(true, true) to snap to end state before starting a new animation. Consider Velocity.js as a faster drop-in for jQuery .animate() that uses rAF internally.
