While I am currently trying to teach myself Haskell for exactly this reason (understand the "real big picture" in FP), I don't know if there is much harm in starting the journey by exploring some FP concepts in languages one is already familiar with, despite how lacking the language is in that regard. This presentation does point out many features that JavaScript lacks from "true FP" languages. I, for one, don't know if I would have ever tried to start learning Haskell if I didn't discover some of the benefits of FP first hand through a familiar language.
