The idea of pure functions deriving UI from state is the single central idea of React's worldview. The docs work extra hard to get this model of apps into your brain. This is not the same thing as people being elitist about Git, this is refusing to engage with the design of the framework and blaming the framework.

I like how you say "others might not be so diligent to have read the docs"... As opposed to? Picking up a UI framework and just winging your way through LSP autocompletions until something happens on your screen?
