I wouldn’t say the same no matter the domain - junior devs can and will surprise you, and because React gives you less guardrails for app architecture, it likely has the potential to go far worse.

Well obviously they'll be CR'd. If you stick to prop drilling and functional code there's far less you can do abjectly wrong.

Except wire up routing in a strange way, or pick a library for form validation or form framework, or come up with odd ways of structuring tests, picking a strange approach for animations, etc.

This is the cost when app architecture gets delegated to your developers over a high quality central solution, the quality is as good as your developers.

Those are the parts where you put a senior in charge. Hell I can't even do that in React, and have in the past literally hired a contractor to set that up for me.

Juniors new to React are unlikely to do so, IME (as a semi-new-to-React not-junior working on a team with new-to-React junior-ish devs -- by experience; there isn't a formal junior/not-junior distinction on our team.)

OTOH, if you do things you really shouldn't do in React, while they won't all be flagged, there's a very high probability it will result in at least related warnings pointing to it in the devtools console, so that's something.
