In many [[programming language]]s, '''map''' is the name of a [[higher-order function]] that applies a [[procedural parameter|given function]] to each element of a [[functor]], e.g. a [[list (computing)|list]], returning a list of results in the same order. It is often called ''apply-to-all'' when considered in [[functional form]].
