Whether you're just beginning, or ready to put principles into practice, we're your guide.

Access to everything: $29/month.

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.
