Having been around this block (procedural->OOP->FP->...) a couple of times over the past 20 years, I've ended up at place where I always start with no classes and mostly pure functions, but don't shy away from adding small handful of classes when it becomes obvious that they solve a real problem. Sometimes objects really are the cleanest solutions, but they should never be your first solution.
