Genuine question, and this seems to be as good a place as any to ask it. I understand the concepts behind functional programming, and trying to implement them in JavaScript (recently read Functional JavaScript too).

But from my experience, functional programming is mainly useful for parallelization/distribution of computation, because it's essentially mathematical -- functional code tends to be harder to write, understand, and debug, but you do it when you need to be able to split up computation. Kind of like assembly is harder than C++, but you do it when you need 100% optimized computation in a section of your program.

But because there is obviously no multithreading in JavaScript, I've never found a compelling reason to use the FP paradigm in JavaScript. Can anyone enlighten me as to real-world situations where FP makes sense in JavaScript, either client- or server-side? Particularly in web-based projects, which is obviously what JS is for?
