Introductio to functional programming using Haskell

After the success of the first edition of Introduction to Functional Programming, the authors have thoroughly updated and revised this bestselling title. This book is unusual amongst books on functional programming in that it is primarily directed towards the concepts of functional programming, rather than their realization in a specific programming language. The book clearly expounds the construction of functional programs as a process of mathematical calculation, but the mathematics is restricted to that relevant to the actual construction of programs.
