A modern programming language that makes developers happier.

Did anyone ever had a common project mixing scala.js and kotlin-js? Maybe someone could recommend an actor framework similar to Akka.js or comedy without leaving kotlin-js? Huge thanks

Kotlin-JS fully supports coroutines which is more powerful than Akka in most cases (not in all though).

Mixing scala and kotlin is in general a bad idea.

Yeah fair enough for Scala - does seem to be a bad idea

For actors I don't agree. I do find it easier to manage resources and build fault tolerance strategies through actors. But that's a personal point of view.

Actors are only one of many asynchronous programming tools. While Akka has in-depth coverage for actors, coroutines in kotlin cover much broader area. And there are actors as well (though they are under redesign right now).
