> the mistake that many FP advocates make is to make it a war of FP vs anything else.
I don't disagree with this (goodness knows there are plenty of functional purists who come across as religious zealots), but I think it's also worth mentioning that there's an opposing camp of people who are hard-set against ever considering FP for anything at all because they've bought fully into object orientation and stateful computation.
Both solutions are well-suited to certain kinds of problems, and this opposition is well summarized by study of what is called the Expression Problem[0]. A good developer should know both paradigms (in addition to others!) and use each where it is best suited.
[0] There are other issues than those discussed by the EP, but the EP is, I think, the most simple perspective of the distinction between OOP and FP.
Edit: TIL you cannot escape an asterisk on HN. That's a bummer.
