Book of Monads

About the Book

Monads are key to unlocking many powerful patterns in functional programming. Alas, many developers struggle at first with the concept and the applications of monads. This books provides a full dive into the subject, including thorough explanations of adjacent concepts such as functors, monad transformers, final tagless, or extensible effects.
