code reusability

Code reusability refers to the practice of writing code in a way that it can be used multiple times across different parts of a project or even in different projects. Instead of creating new code for each task, developers design modules or functions that perform common tasks once and then reuse them whenever needed. This approach saves time, reduces errors, and makes updates easier, since changes made in one place automatically affect all areas that use that code. Essentially, it's about creating versatile building blocks that can be applied repeatedly, improving efficiency and consistency in software development.
