The selling point of scala, at least in theory, is that it combines all features of OOP and functional programming. Before I found out about elixir, I found akka actors a extremely nice abstraction, as they are a copy of erlang processes.
I revisited the language about 6 months ago and I must say that I am not impressed, for example their implementation of monads as collections and usage of for comprehension in the way we use with in elixir is hacky to say at the very least.
I guess you would usually use scala when you have to interact with existing java code and want to make your project use some of the more advanced FP features, even though I would argue that Kotlin is a much better alternative these days, you have there finally a nice abstraction for concurrency and the syntax is much nicer, even if you don’t have more advanced FP features.
