I understand "just a view library" might have been used to contrast it to full framworks that dictate a lot more than React, but it's important to note that the key React feature compared to other view libraries is precisely that it's not "just a view library": state is at its core.

It's hard to disagree with the the pain of React having to leave the comfort of plain idiomatic JS to better fulfill its goal, but to me React's efforts are in a way an experiment to find some primitives that should be baked into JS engines to allow for these mature, fine tuned experiences without putting the burden on the library.
