React Native GRACEFULLY handles multiple platforms. The vast majority of the React Native APIs are cross-platform, so you just need to write one React Native component, and it will work seamlessly on both iOS and ANDROID. Facebook claims that their Ad Manager application has 87% CODE reuse across the two platforms, and I wrote a flashcard app without any platform-specific code at all.

If you do want to write platform-specific code -- due to different interaction guidelines on iOS and Android, for instance, or because you want to take advantage of a platform-specific API -- that's easy, too. React Native allows you to specify platform-specific versions of each component, which you can then integrate into the rest of your React Native application.
