Haskell Fundamentals

Foundational Haskell patterns and core language features for pure functional programming. This skill serves as both a reference for common patterns and foundation for advanced Haskell development.

Overview

This skill covers:

• Pure functions and immutability
• Type system and type inference
• Type classes (Functor, Applicative, Monad)
• Pattern matching and guards
• List comprehensions and recursion
• Common monads (Maybe, Either, IO, State)
• Function composition and higher-order functions
• Lazy evaluation fundamentals
