Who we are:

Type Classes is Julie Moronuki and Chris Martin, producing videos and writing to help you experience the joy of pure functional programming.

What you can expect as a subscriber:

  • Focused, coherent video courses covering topics in Haskell and Nix.
  • Practical projects, presented in video and text.
  • Clear, approachable articles for all levels, whatever your background.

We believe that it’s important to approach Haskell from different perspectives. In addition to the structured courses, therefore, we also provide a range of materials to supplement the courses:

  • Videos and articles aimed at programmers coming from other languages that show direct comparisons between X in Python, Java, or other languages and how to represent that in Haskell.
  • Programming principles and mathematical concepts.
  • Other functional languages and tools, especially Nix and NixOS.
