functor [′fəŋk·tər]

(computer science)

logic element

(mathematics)

A function between categories which associates objects with objects and morphisms with morphisms.

functor - In category theory, a functor F is an operator on types. F is also considered to be a polymorphic operator on functions with the type

F : (a -> b) -> (F a -> F b).

Functors are a generalisation of the function "map". The type operator in this case takes a type T and returns type "list of T". The map function takes a function and applies it to each element of a list.
