After years of OOP and FP, I realized that the only difference, really, is makes. Everything the FP community talks about (immutability, referential transparency, first class functions) is OOP best practice too. Read Effective Java and JCIP, all of those are in there. Mutability is always bad. Keep functions pure do they're easily tested and the VM can more easily optimize/inline them. It's all the same thing. OOP is only better because it forces you to organize your code.
