a design pattern , inspired by the definition from category theorythat allows for a generic type to apply a function inside without changing the structure of the generic type

In functional programming, a functor is a design pattern inspired by the definition from category theory, that allows for a generic type to apply a function inside without changing the structure of the generic type.

In category theory

In Category Theory, a Functor is a morphism between categories, that is, categories maps each object in category A to another object in B, as well as mapping each morphism C -> D onto the respective ...
