Webfold is by far the most common recursion-scheme, because working one layer at a time is the most common strategy for writing a recursive function. But there are also other, rarer strategies. Researchers have given names to the most common strategies, and their name for fold is "catamorphism".

It is a higher-order recursive function which takes a non-recursive function as an argument. That non-recursive function describes the part which is unique to your calculation: the "what". Types with many constructors Let's look at … See more Here are two recursive functions. These functions are very similar. In both cases, the empty list is the base case. In the cons case, each makes a recursive call on the tail of the list. Then, … See more Let's look at a more complex example.
