About this course

Let me ask you a question. Do Haskellers really use these concepts as often as it seems?

  • This course takes you on a journey from simple examples (lists, trees, optionals) to the more generic ideas.

  • The goal is to develop your intuition about what functors, monads, and applicatives are and the main use cases for each of them.

  • We provide not only explanations, but also exercises for you to follow along.
