If you've been trying to get into functional programming, there's a good chance you've heard of composition and piping. These concepts apply to point-free programming. This is an attempt at a simple, clear explanation of function composition and piping. I will write these examples in F#, but the concepts apply to other languages like Haskell. They just use different operators sometimes.

Prerequisites: basic programming knowledge. This explanation is going to be simple.

Piping
Let's begin with the simpler of the two (at least according to my experience): piping. There are two ways which you could pipe a value to a function. Forwards, and backwards. When you pipe forward, you are applying the left side of the forward
