Higher-order function — In mathematics and computer science, higher order functions or functionals are functions which do at least one of the following: *take one or more functions as an input *output a function.In mathematics these are also known as operators or… … Wikipedia
Fold (higher-order function) — In functional programming, fold, also known variously as reduce, accumulate, compress or inject, is a family of higher order functions that process a data structure in some order and build up a return value. Typically, a fold deals with two… … Wikipedia
Map (higher-order function) — In many programming languages, map is the name of a higher order function that applies a given function to each element of a list, returning a list of results. They are examples of both catamorphisms and anamorphisms. This is often called apply… … Wikipedia
Filter (higher-order function) — In functional programming, filter is a higher order function that processes a data structure (typically a list) in some order to produce a new data structure containing exactly those elements of the original data structure for which a given… … Wikipedia
Higher order programming — is a style of programming that exploits the theoretical ability to use functions as values; it is usually instantiated with, or borrowed from, models of computation like the lambda calculus which make heavy use of higher order functions.For… … Wikipedia
