Kindle Edition (forthcoming)
This book presents an introduction to functional programming in Haskell. As a purely functional language, Haskell supports the development of programs that consist of cooperating functions and data types. Topics include numeric, text, and list processing, in applications ranging from the simple to the complex. The reader will learn how to write code that is joyful to read and easy to verify. For experienced programmers who want to learn a new way of doing things, or beginners who want the challenge of learning to code in a strict and safe programming environment.
Included features
- A gentle, just-in-time approach, where no concept is introduced before it is needed
- A discussion of the basic ideas of functional programming, such as recursion, higher-order functions, algebraic data types, generic types, and type classes
- Realistic applications, including numerical computation and text-based computation
- End-of-section programming exercises to try out the ideas presented
- Complete program examples, from the simple to the complex, also available on the author’s Web site
