Reusability in software refers to the ability of software components or modules to be used in multiple contexts or applications without significant modification. It allows developers to create generic, modular, and flexible code that can be easily adapted and reused for different projects or functionalities. Reusability promotes efficiency, as developers can leverage existing code instead of rewriting it from scratch. It also enhances maintainability, as changes or updates made to a reusable component can automatically propagate to all the applications or systems that use it. There are different levels of reusability in software, ranging from small code snippets or libraries to entire frameworks or platforms. Common techniques for achieving reusability include creating well-documented and self-contained modules, using standardized interfaces and protocols, adhering to design patterns and architectural principles, and leveraging object-oriented programming concepts like inheritance and polymorphism. By promoting code reuse, reusability reduces development time, effort, and costs while improving software quality and consistency across projects. # References ```dataview Table title as Title, authors as Authors where contains(subject, "reuse") or contains(subject, "reusability") ```
