Higher-order function
In
mathematics
and
computer science
, a
higher-order function
(also
functional
,
functional form
or
functor
; not to be confused with the
functor
concept in
category theory
) is a
function
that does at least one of the following:
takes one or more functions as arguments,
returns a function as its result.
All other functions are
first-order functions
. In mathematics higher-order functions are also known as
operators
or
functionals
. The
differential operator
in
calculus
is a common example, since it maps a function to its
derivative
, also a function.
