You’ll now turn your attention to looking at some of the core programming patterns that differentiate functional code from imperative and that you’ll use to structure the flow of your functional code. You’ll first look at some ways to use map, filter, and reduce functions to perform common operations on sets of data. They’re useful in most scenarios where, as an imperative programmer, you would have used loops based on foreach or for to iterate through ...
