I originally did it just to become a little bit more sharp in these languages, but what I found was really interesting, so I thought I would share my findings in a blog post. What is a Linked List? A linked list is one of the most foundational data structures in computer science.

Haskell is also lazy-evaluated, meaning that any code that isn’t needed for a return value in a function is never evaluated.

In this short blog post, I will explain the difference between data, type, newtype, class, and instance keywords in haskell and how they all work together. This is not meant to be an in-depth tutorial, but just a reference guide. If you program occasionally in haskell and just want a quick reference, bookmark this page. data: This just defines a new data type in haskell. Several examples are below: Record Syntax (a row in a database):
