Going Functional

Welcome to the world of Haskell! Before looking too deeply at the language itself, you will learn about what makes Haskell different from other languages and what benefits come with those differences. Haskell belongs to the family of functional languages, a broad set that includes ML, Lisp, Scala, and Clojure. If you have a background mostly in imperative or object-oriented languages, such as C, C++, or Java, you will see which of the ideas present in those languages can be transported into the functional world. If you already have experience with functional languages, you will see how other features in Haskell, such as lazy evaluation and type classes, make this language different from any other.
