A modern programming language that makes developers happier.

kotlinlang

I'm about to start a greenfield React project, and I'm wondering how realistic a choice Kotlin is -- the project will only need a couple of months development, and then will be relatively unchanged after that, so I'm concerned about the stability of the tooling and potentially unpleasant future migrations given how young the Kotlin/JS/React ecosystem is. If not Kotlin, I'd most likely use TypeScript. Elm is neat, but I don't want to completely confuse other people who look at the code (which is a downside for Kotlin as well). Thoughts?
