If you use react native on mobile and react on the web the core model and business logic can easily be shared since it is just pure js. And you can use any of the languages that transpiles to js: TypeScript, Clojurescript etc.

What about performance and the "overhead" that React Native might introduce?

The performance is impacted, avoiding premature optimizations I haven't looked into that part yet though. Without any performance optimizations I'm experiencing performance better than HTML5 but not really on par with native. To me the value of sharing the logic and the crazy fast development speed is more valuable than a few milliseconds of delay. At least in this stage.
