Or dart and flutter - all 4 being supposed first class citizens at Google.
My personal philosophy has been to solve/implement the issue at hand using a language that I consider to have "native" proficiency. Because, the list of languages propping up claiming to be the next best thing is large:
1. Kotlin
2. Go
3. Dart/flutter
4. Rust
5. Swift
6. Scala
7. Haskell
8. F#
The advent of llvm has drastically cut down the time to market for new languages. I'm certain a few more will get added to this list soon, so just get the job done following best practices and without incurring technical debt. This will make your work language proof
