Get Programming with Haskell

**Summary** __Get Programming with Haskell__ introduces you to the Haskell language without drowning you in academic jargon and heavy functional programming theory. By working through 43 easy-to-follow lessons, you'll learn Haskell the best possible wayпїЅby doing Haskell! **About the Technology** Programming languages often differ only around the edgesпїЅa few keywords, libraries, or platform choices. Haskell gives you an entirely new point of view. To the software pioneer Alan Kay, a change in perspective can be worth 80 IQ points and Haskellers agree on the dramatic bene ts of thinking the Haskell wayпїЅthinking functionally, with type safety, mathematical certainty, and more. In this hands-on book, thatпїЅs exactly what youпїЅll learn to do. **About the Book** __Get Programming with Haskell__ leads you through short lessons, examples, and exercises designed to make Haskell your own. It has crystal-clear illustrations and guided practice. You will write and test dozens of interesting programs and dive into custom Haskell modules. You will gain a new perspective on programming plus the practical ability to use Haskell in the everyday world. (The 80 IQ points: not guaranteed.) **WhatпїЅs inside** - Thinking in Haskell - Functional programming basics - Programming in types - Real-world applications for Haskell **About the Reader** Written for readers who know one or more programming languages. **About the Author** Will Kurt currently works as a data scientist. He writes a blog at www.countbayesie.com, explaining data science to normal people.

Appendix - Sample answers to exercise Unlike any other programming language, Haskell is purely functional with a strong type system and lazy evaluation. It is arguable the most interesting language but also has the reputation of being one of the most challenging to learn. Learning Haskell doesn't have to be difficult, and this book can help! Learn Haskell teaches readers the Haskell language and functional programming concepts while they hack on interesting problems that are challenging but never frustrating. This example-filled tutorial will take users from the basics to tackling the tough topics. There are lots of crystal-clear illustrations, hands-on exercises, and open-ended tasks that encourage readers to explore Haskell on their own. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. Get Programming with Haskell introduces you to the Haskell language without drowning you in academic jargon and heavy functional programming theory. By working through 43 easy-to-follow lessons, you'll learn Haskell by doing Haskell. This book starts with first concepts, building your knowledge with concrete examples and exercises. You'll learn to think the Haskell way, as you start to understand the language and how to use it effectively. And you'll really appreciate the crystal-clear illustrations, quick-checks, and open-ended tasks that make sure you're solid on each new concept before you move along!
