I used react for one year, for the web, but not react native. I'll be honest: once I got fluent in react, I still didn't enjoy it.

Too much scrolling around, looking up the doc for every simple things, hard to integrate with legacy Python/Ruby/PHP frameworks, etc.

I went from jQuery then Angular 1, and was much less productive in React.

Also, introducing react to a new member in the team has always been dreadful.

All in all, I never benefited from the concurrency part. The performance yes, and the structure for the SPA. But the whole immutable constraint didn't pay off for me in the end, so I felt my stack was overkill.
