Depends on what you mean by "FP-ish". I never saw this code, but the way this was described to me as high church FP, the kind of people who really wanted to be working in an ivory tower FP language and so had coded as if that's what they were using. I don't think it's unreasonable for average Javascript programmers to look at that and say, "WTF", the same way that they'd look at code from somebody who wrote C in Javascript.
