Also they were kind of time constrained. WebGL would have been definitely more performant but it has all sorts of hardware issues at times in different devices. I've done plenty of WebGL over the years and seen random GPU crashes where you have to restart the entire machine to unlock your self out.

The canvas trick with typed arrays is brilliant. Using requestAnimationFrame is what any front end dev who knows perf would do. Its like the front end version of cdn with 1 second time out trick.

Also using a layer of library whose code you don't understand in a perf critical application is quite risky. Its better to stick closer to the native browser APIs which you are familiar with. We once had to throw away a library and rewrite code from scratch because their assumptions failed when pushed to the limits. The rewritten code was 100x smaller in size and 10x more performant.

I would have loved to work on something like this but it sucks reddit doesn't have any presence in Seattle.
