I am talking about virtualized lists. And it should be a framework feature. I used to use WPF on desktop, and it had pretty good virtualization support (though the framework in general was more like Angular) - most containers had virtualization support, and you only had to implement the logic on the data source, and they framework created and managed physical UI elements for you, and managed the mapping so it seemed seamless to the user.
React also operates on a virtual dom, there's no reason imo why couldn't they just fake that for you.
I mean, it's not quite that easy. The web is a lot more dynamic than WPF. If you just want virtualized homogeneous lists, there are libraries for that (and grids).
But, once you start hitting things like differently sized elements, search and so on, you start running into platform limitations that you won't be able to resolve in React land.
