Three Reasons to Learn Haskell

Three Reasons to Learn Haskell

If you’re familiar with functional programming, you’ve likely heard of Haskell. This advanced, purely functional programming language is attractive to companies using large amounts of data, and it’s been used by companies like Google, Facebook, Twitter, and Microsoft in various capacities.

But with all the other languages out there, why should someone consider learning Haskell? Let’s briefly look at a few reasons.

 

3 Reasons to Learn Haskell

1. Haskell helps cement your knowledge of FP

Every function in this “purely functional” language is a function in the mathematical sense. And, rather than telling the computer what to do, you essentially explain what the function is and what it does. Haskell really enforces functional programming rules, which greatly reduces a program’s complexity while maximizing the language’s functional potential.

2. Learning Haskell teaches you to think with immutable data

Immutability refers to data or objects that can’t be modified after creation. Expressions in Haskell are immutable, which makes for effortless refactoring, helps avoid unintended side effects, and makes the code much easier to reason about.

3. After you learn Haskell, you’ll finally understand Monads!

Many people find it challenging to explain what monads are. That’s because the only way to really understand monads is to learn Haskell. OK, not really. But it certainly helps. In simple terms, monads are abstraction that allow structuring programs generically. It essentially provides a way to use imperative programming in functional programming. Monad is a type class in Haskell. So you can use it to define basic operations and functions for those instances. They allow you to structure a program by describing computations as sequences of steps, and they handle side effects too. Bottom line: Monads are handy little bundles of magic that can make your life easier and reduce boilerplate code. When you learn Haskell, you’ll also learn to appreciate the benefits of monads.
