Category Theory via C# (5) Bifunctor
A functor is the mapping from 1 object to another object, with a “Select” ability to map 1 morphism to another morphism. A bifunctor (binary functor), as the name implies, is the mapping from 2 objects and from 2 morphisms. Giving category C, D and E, bifunctor F from category C, D to E is a structure-preserving morphism from C, D to E, denoted F: C × D → E:
