So I'm not a fan of metaprogramming or heavy abuse of tricks for convenience either, and I do get and agree with your point!

But for some anecdotal nuance concerning the React example: > Take React for example. It's an abstraction, arguably a new "language", and requires ample documentation and usability concessions to be palatable. You could accomplish this with macros as well.

I feel like the standard before React was just every (web) framework inventing its own templating language, whereas I found React to be really easy to learn, because the way it abstracted things were straightforward and well explained. It's tooling however is one of the scariest things I've ever seen haha.
