One thing that we've seen already in Haskell programs is type classes. Today, we're going to try to take our first look real look at them in detail - both how to use them, and how to define them....

So, we've built up some pretty nifty binary trees - we can use the binary tree both as the basis of an implementation of a set, or as an implementation of a dictionary. But our implementation has had one...

In Haskell, there are no looping constructs. Instead, there are two alternatives: there are list iteration constructs (like foldl which we've seen before), and tail recursion. Let me say, up front, that in Haskell if you find yourself writing...

Last time around, I walked through the implementation of a very simple binary search tree. The implementation that I showed was reasonable, if not great, but it had two major limitations. First, it uses equality testing for the search,...

For this post, I'm doing a bit of an experiment. Haskell includes a "literate" syntax mode. In literate mode, and text that doesn't start with a ">" sign is considered a comment. So this entire post can be copied...

Haskell is a strongly typed language. In fact, the type system in Haskell is both stricter and more expressive than any type system I've seen for any non-functional language. The moment we get beyond writing trivial integer-based functions, the type...

I wasn't really sure of quite how to start this off. I finally decided to just dive right in with a simple function definition, and then give you a bit of a tour of how Haskell works by showing the...

Before getting to the meat of the tutorial, I thought it would be good to provide some setup information in a distinct, easy to find place. This short post will tell you where to find a Haskell implementation and related...

Before diving in and starting to explain Haskell, I thought it would be good to take a moment and answer the most important question before we start: Why should you want to learn Haskell? It's always surprised me how many...
