Is it worth getting into React Native now or should I wait?

The answer, as with (almost) anything in software development, is it depends.

I jumped right into it because I am building an isomorphic React website for a community - using React Native just makes supreme sense for this use case since I can reuse my React service code across my backend, web frontend, and iOS (and Android whenever React Native adds support).

It may not be the perfect solution to every problem, but it works so nicely for me since I am doing this on the side with only junior developers & a mid/senior developer to help. There is no reason for me to reinvent the wheel here.

If its for production use, I would think about it twice, and analyze the other options first.

Nothing is stopping you from jumping in. Just brace for a rough ride.
