What Hacker News says
3 sources>But this does fall apart for very very large grids, as you get close to the height limit described in this article.
This was solved by a now unmaintained virtualization library that predates both of these libraries: https://github.com/bvaughn/react-virtualized
The react-virtualized library works around this issue by scaling the the scroll position it sets for a row based on the ratio of "max CSS height allowed by browser" to "computed height of all rows" if the latter is greater than the former: https://github.com/bvaughn/react-virtualized/blob/master/sou...
In Infinite PixelsMake a demo with react-virtualized[0] and see if it crashes. Hint: It will not[1]. React can easily render 1 million rows with high performance without relying on WASM [2]
Here is the demo of react-virtualized[3], in which I entered 10m as the row count and scrolled to the bottom without crashing.
