Functions

Code on demand.

In computer programming, a function, procedure, method, subroutine, routine, or subprogram is a callable unit[1] of software logic that has a well-defined interface and behavior and can be invoked multiple times. Callable units provide a powerful programming tool.[2] The primary purpose is to allow for the decomposition of a large and/or complicated problem into chunks that have relatively low cognitive load and to assign the chunks meaningful names (unless they are anonymous). Judicious application can reduce the cost of developing and maintaining software, while increasing its quality and reliability.[3]
