Ask HN: In-depth source for learning RamdaJS

My new year's resolution is to "get functional". I have already started with Haskell[1] and now, I want to start using FP in some toy project.

I find RamdaJS to be a perfect fit. But I can't seem to find a good, i.e. in-depth, guide on the topic.

Anyone knows a good place to start?
