So the single most important factor that differentiates front-end frameworks is DOM diffing performance?

Well, IIRC, Elm is faster than all the examples given, and yet front-end developers find Elm to be weird and frightening.

So I’m not sure I agree with the premise of the article.

I also don’t agree that there can be so many valid answers to “Find a change detection paradigm that fits the needs of your application”. Surely everyone just needs the one that is most efficient and least broken.
