Rediscovering Haskell: A Beginner’s Guide to Functional Programming

If you’ve found yourself yearning to revisit the intriguing world of Haskell, you’re not alone. The Haskell programming language can feel daunting, especially if you’ve dabbled with it in the past and are now looking for a fresh start. With a background in functional programming using languages such as Ruby, you’re already on the right path to rediscovering its nuances and complexities. This guide aims to offer you a structured pathway to dive back into Haskell.

Why Haskell?

Before we jump into resources, let’s understand why Haskell is a valuable language to learn or relearn:

  • Functional Programming Paradigm: Haskell is purely functional, meaning functions are first-class citizens. This leads to clearer and more concise code.
  • Strong Static Typing: Haskell’s type system helps catch errors at compile time, which can save you time debugging.
  • Lazy Evaluation: It only computes what you need when you need it, improving performance in certain scenarios.

Getting Started with Haskell

As you ease back into Haskell, having the right resources is crucial. Below are some excellent links and materials that will guide you through this journey:
