Maybe Haskell

What would it be like to program in a language without the frustrating concept of null? In our new book, Maybe Haskell, we explore exactly this. Haskell takes the idea that some values may not be present and makes it a first-class concept in the type system. In this book, you'll learn just enough Haskell to really see how this idea works in practice.
