Learn You a Haskell for Great Good!: A Beginner's Guideby Miran Lipovaca
Synopses & Reviews
It's all in the name: Learn You a Haskell for Great Good! 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.
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.
As you work your way through the author's imaginative (and occasionally insane) examples, you'll learn to:
Short of eating the author's brain, you will not find a better way to learn this powerful language than reading Learn You a Haskell for Great Good!
Book News Annotation:
Targeting programmers experienced with traditional imperative programming languages such as C++ or Java, but also accessible to those new to computer languages, this beginner's guide to the Haskel functional programming language examines the unique characteristics of Haskell and provides step-by-step instructions for getting started with this interesting and unusual language. The volume covers syntax and functions, modules, inputs and outputs as well as Haskell specific concepts and advice about thinking in a functional programming manner. The work includes numerous code examples and access to additional online resources is provided. Lipovaca is a computer science student from Slovenia.
