Haskell is most likely quite different from any language you've ever used before. Compared to the usual set of concepts in a programmer's mental toolbox, functional programming offers us a profoundly different way to think about software. In Haskell, we de-emphasise code that modifies data.
I sometimes use Haskell to solve Project Euler problems. When I do use it, I end up learning many new concepts in functional programming, such map/filter/fold, infinite lists, converting iterative algorithms to recursive functions, memoization, etc. To run a Haskell solution, run the Haskell file as a main program.
