scala is intended to provide full support for both functional and object oriented programming. the positive side is that it will support programming in whatever style you like, or any mix in of styles. the negative side is that it is a huge language with a complex type system, and that the library ecosystem has a mix of various styles, e.g. there is scalaz which is heavily inspired by more purely functional languages like haskell, and scalaz code will look totally bizarre to you if you have mainly been using the object oriented features of scala. (contrast with go, which is on the opposite end of the spectrum in that a design goal is that go code should look familiar no matter where you see it, because the language supports a very constrained style of programming)
