Haskell Data Types Review!

This week we're taking a quick break from new content. We've added our new series on Haskell's data system to our permanent collection. You can find it under the beginners panel or check it out here! This series had five parts. Let's take a quick review:

1. In part 1 we reviewed the basic way to construct data types in Haskell. We compared this to the syntax of other langauges like Java and Python.
2. Part 2 showed the simple way we can extend our Haskell types to make them sum types! We saw that this is a more difficult process in other languages. In fact, we resorted to making different inherited types in object oriented languages.
3. Next, we demonstrated the concept of parametric types in part 3. We saw how little we needed to add to Haskell's definitions to make this work. Again, we looked at comparable examples in other languages as well.
4. In part 4, we delved into Haskell's typeclasses. We compared them against inherited types from OO languages and noted some pros and cons.
5. Finally, in part 5 we concluded the series by exploring the idea of type families. Our code was more complicated than we'd need in other languages. And yet, our code contains a lot more behavioral guarantees in Haskell than it does elsewhere. And we achieved this while still having a good deal of flexibility. Type families have a definite learning curve, but they're a useful concept to know.
