Learn Haskell by doing Haskell projects! In this book, you'll get practical experience writing Haskell code and applying functional programming to actual development challenges.
In Learn Haskell by Example, you'll build your Haskell skills by working through hands-on challenges and conundrums. You'll learn to look at each project through a Haskell lens, and then solve it using features like lazy evaluation, immutable data structures, and monads.
In Learn Haskell by Example you will learn how to
Use Haskell for daily programming tasks
Effectively apply functional concepts
Avoid common beginner pitfalls of Haskell
Apply abstract concepts in the Haskell language
Debug and profile Haskell applications
Improve the performance of Haskell applications
Haskell is an amazing choice for applications that need an extra guarantee of safety, such as in smart contracts, data intensive applications, and large scale distributed systems. In this book, you'll see just how practical Haskell can be for creating programs by building your own engaging projects! Learn how to structure real-world applications, how to work with the Haskell tool chain effectively, and what to look out for when writing critical sections in the program's logic. Best of all, each project in this book is fully extensible and customizable so you can keep tinkering with your favorites!
About the Technology
Programmers spend a lot of time debugging and refactoring code, reading comments and documentation, and trying to make sense out of complex designs. Haskell, a powerful, beautiful, and challenging functional programming language, promises a different path. By focusing your attention on simple functions, clearly-defined behaviors, and the right high-level abstractions, Haskell disallows the dangerous behaviors that usually lead to bugs and crashes.
About the Book
Learn Haskell by Example teaches you to build applications in Haskell by designing and coding fun and engaging projects. In this easy-to-follow guide, you'll create a domain specific language for music, an image processing library, and more! You'll learn Haskell from the ground-up with a focus on important concepts like function design, composition, and data immutability. Each project gives you a new insight into how to think in Haskell and helps you understand why many Haskell developers say they will never use another language again.
