7. FP Is Like Unix Pipeline Commands (Functional Programming in Depth)
The primary goal of this lesson is to show that you can think of writing functional programs as being like writing Unix pipeline commands. Stated another way, if you’ve written Unix pipeline commands before, you have probably written code in a functional style, whether you knew it or not.
As a second, smaller goal, I want to demonstrate a few ways that you can look at your code visually to help you “Think in FP.”
