series_index	Recursive types and folds	Recursive types and folds

In this series, we'll look at recursive types and how to use them, and on the way, we'll look at catamorphisms, tail recursion, the difference between left and right folds, and more.

• Introduction to recursive types. Don't fear the catamorphism....
• Catamorphism examples. Applying the rules to other domains.
• Introducing Folds. Threading state through a recursive data structure.
• Understanding Folds. Recursion vs. iteration.
• Generic recursive types. Implementing a domain in three ways.
• Trees in the real world. Examples using databases, JSON and error handling.
