Learn You a Haskell for Great Good!

Free online book “Learn You a Haskell for Great Good!” by Miran Lipovaca is a hilarious, illustrated guide to this complex functional language. Packed with the author’s original artwork, pop culture references, and most importantly, useful example code, this book teaches functional fundamentals in a way you never thought possible.

Book Description

You’ll start with the kid stuff: basic syntax, recursion, types and type classes. Then once you’ve got the basics down, the real black belt master-class begins: you’ll learn to use applicative functors, monads, zippers, and all the other mythical Haskell constructs you’ve only read about in storybooks.
