I've studied scala for several months, but still at the beginner level. Now I found I have huge trouble with functional programming and scala's type system.
I tried finding some documents and blogs, but I can't understand most of them(especially type-system ones). So I'm looking for some small and good scala projects that I can read the sources to learn.
Could you please recommend me some?
There's a popular set of "Scala Problems" out there, called the 99 Scala Problems
Problems come in all difficulties, and many flavors, basic functional programming included.
