Introduction to Functional Programming with Haskell: Key concepts of functional programming such as immutability, pure functions, and first-class func

Think Functionally - Code Elegantly with Haskell.

Step into the world of functional programming with Haskell, one of the most powerful and expressive programming languages ever created. This beginner-friendly guide introduces you to the core principles of functional thinking and shows you how to write clean, predictable, and bug-resistant code using pure functions, immutability, recursion, and first-class functions.

Whether you're a self-taught developer, a CS student, or a seasoned coder curious about functional programming, this book provides a hands-on, example-driven approach to learning Haskell from the ground up.
