DescriptionFree EBook on Haskell Programming
Haskell is a functional programming language. If you have programmed before and would like to see a little bit of how Haskell works and is different from other programming languages, you can get an overview in this ebook.
Haskell is unique for two reasons. The first is that it is purely functional. If you have a function and you call it twice in two different places with the same arguments then it will return exactly the same value both times. Secondly, Haskell provides a very modern type system which incorporates features like typeclasses and generalized algebraic data types.
So, why do Haskellers like the language then? Is it just because we like using things that are unique and modern? No, Haskell programmers enjoy their work because dealing with just pure functions makes it so much easier to understand our programs and prove them correct. Moreover, having an advanced type system helps us catch our mistakes, both the silly and profound ones.
In this book we aim to introduce you both to the Haskell language, from the very basics to its most advanced features, and to computer programming in general.
