> insane knowledge of the browser rendering pipeline to solve Saying it having not much of that knowledge myself: it's reasonable to sometimes need platform knowledge to make intricate things (here a realtime animation) behave efficiently. That's the same for game engines, native rendering, flash animations etc. There will always be edge cases, building enough stuff you'll hit them, and if you care about doing it right it will require knowledge to overcome the issues.
