Thinking about Haskell?Get started
There is so much in Haskell to love. Let us help you discover it all.
Why Type Classes
How do you learn a programming language?
- Books start from basics and build up, and along the way can introduce you to things you might not have known you needed.
- Good documentation gives a concise summary of how to use something, if you already have the context and know what you’re looking for.
Why not have both? In one place, with consistent style and quality. That’s Type Classes.
Type Classes membership offers a combination of book-like courses and documentation for Haskell features, linked together into a single resource.
Our top-quality courses and documentation include some things that no other Haskell resource does:
- Hyper-practical demonstrations to get you writing programs quickly
- Series with a coherent narrative arc that explore a topic in great depth
- Comparative literature specifically aimed at helping you transition to Haskell from other languages
- View the course list or the complete list of pages
- Peruse the topics in the index
We’ve added a page on
Seqand an explanation of the basics of time complexity.
Applicative lesson 11, identity and interchange, is up!
Applicative lesson 10, homomorphism and composition, is now available. As I mentioned yesterday, these lessons have taken a lot …
Thanks for Type Classes and all you provide to the Haskell community. It’s helped me go from a longtime Haskell “lurker” to someone now using Haskell professionally. – Matt Revelle
… a masterclass in documentation … – Craig Dallimore
Really informative courses @typeclasses! Highly recommended to anyone who is interested in FP. The more I read the more I realise I don’t know anything about most things anymore. – @mmgalea
I’m really enjoying @typeclasses. The validation course is a real tour de force that makes Monads easy to understand and really provides the context and justification. – @wennefer
Typeclasses is very good. I didn’t expect I’d learn so much since I already knew Haskell well but there’s lots of interesting nuggets of wisdom around. – Jasper Van der Jeugt
