Use IntersectionObserver for better future performance.

IntersectionObserver is way faster than hooking into the scroll.

Then add the polyfill 👍

w3c/IntersectionObserver#135

Not hooking on to the onscroll event at all! Using requestAnimationFrame, way more preformant than the 100ms delay used in the IntersectionObserver polyfill you posted. IntersectionObserver is looking promising, but i will hold off on implementing untill it's supported on all mayor browsers.

Thanks for the heads up!
