Wikipedia
In software development (and computer programming in general), code reuse, also called software reuse, is the use of existing software, or software knowledge, to build new software,: 7 following the reusability principles.
Code reuse may be achieved by different ways depending on a complexity of a programming language chosen and range from a lower-level approaches like code copy-pasting (e.g. via snippets), simple functions (procedures or subroutines) or a bunch of objects or functions organized into modules (e.g. libraries): 7 or custom namespaces, and packages, frameworks or software suites in higher-levels.
Code reuse implies dependencies which can make code maintainability harder. At least one study found that code reuse reduces technical debt.
