This is terrible and not worthy of HN front.

Terrible from the front-end side of implementation: - performs worse than your average arbitrary-amount-of-rows-that-won't-fit-on-the-screen library (it should perform the same no matter if its 1k, 1m or 1mm rows) - is seemingly buggy - is pointless on its own, because THIS demo is a client-side demo, and no one loads that much data on the client-side.

Revisit this when this demo is performant AND data is loaded from the backend.

Ignoring that, every front-end JS developer should explore these kinds of libs and also try to implement them themselves, because they're basically front-end 101.
