One of the greatest things about Scala is that you can just start if you know Java and be productive. Just write your code like you would in Java, with a slightly different syntax. Then, when you use libraries, you will pick up new concepts step by step. And if you want it so, you can write pure functional code in Scala, similar to Haskell code. If you start with Haskell, you are forced to do pure functional programming. That is much more intimidating and less productive, but also better if you want to force yourself to learn it.
