code reuse

Code reuse refers to the practice of using existing software code for new purposes instead of creating new code from scratch. This approach saves time and effort, reduces errors, and ensures consistency. Typically, developers create reusable code modules, libraries, or functions that can be integrated into various programs. For example, a company might reuse a login function across multiple apps rather than writing new login procedures each time. Overall, code reuse promotes efficiency and maintainability in software development, enabling faster updates and better quality through proven components.
