I've been doing React professionally for 3 years now. I've messed with React Native out of curiosity and to see if it would fit my needs.

React Native remains a hard sell for me. The idea behind it is that knowledge of React is where the learning curve is. Which is a flawed premise. React, itself, is dead simple. But ditching years of CSS and DOM knowledge and learning the React Native component API and quirks regarding iOS and Android? That's a massive hill to climb. Even with JavaScript by your side. I'd rather try Cordova+React if I had to. And if I truly wanted native performance, then it's Obj-C for me. Might as well suck it up and do it right in the first place.
