Dive into the mathematical soul of Haskell with a tour of discrete structures and their elegant implementations. This book covers:

✨ Algebraic Data Types (ADTs) - Model real-world problems with sum and product types.
✨ Combinatorics and recursive algorithms - Solve counting problems with Haskell's toolkit.
✨ Type classes and laws - Harness polymorphism the right way.
✨ Category theory baby steps - Functors, monoids, and the art of abstraction.

Packed with visual analogies and executable examples, this volume bridges the gap between theory and practice. Perfect for hackers who love proofs!
