That's an example of something that can be done well or done poorly.

AirBnB, UberEats and Facebook are all built with React Native and they have excellent performance.

Using a JS framework for your UI doesn't inherently mean it will suck. It can be done well.

If you expect it to be half as much work, you'll be disappointed.

If you expect it to be a tradeoff that makes some things easier and some things harder, and you're willing to invest in making it excellent, then it can be a very reasonable choice.
