The Book of Functions: Explore Set Theory, Abstract Algebra, and Category Theory with Functional Progra mming

By Paul Orland

This surprisingly accessible book uses key math concepts and more than 500 short exercises to teach functional programming to experienced coders.

Functional programming is a coding paradigm that emphasizes functions, repeatable computations that take input data and produce corresponding outputs. Functions are also important concepts in math, and a lot of deep mathematical insights shed light on functional computer programming.

In this book, the author uses functional programming to introduce mathematical concepts - most notably set theory, abstract algebra, and category theory - and in turn uses that math to describe functional programming design patterns. The more than 500 short programming exercises included in the book will help you master functional programming and math skills alike, with code examples presented in the F# language.
