Reusability

In computer science, reusability is the likelihood a segment of structured code can be used again to add new functionalities without modification.

Using reusable code reduces implementation time, increases the likelihood that prior testing and use has eliminated bugs and localizes code modifications when a change in implementation is required.

Subprograms - typically called subroutines or functions - are a simple form of reuse. Objectss and software components offer a more advanced form of reusability.
