Which one is easier? I need to write some cross-platform native code for my React Native app, and I'm having a really hard time deciding on the language. I honestly didn't know that I could use either Kotlin OR Swift for both platforms. But which would be easier to get running on Windows? I also need to write a version that works on the web, and I've heard that Kotlin can transpile to JS. So that's pretty amazing if that works. Otherwise I was considering C, C++, or Rust.
