Can you explain the difference between code reusability and code duplication?

Can you explain the difference between code reusability and code duplication?

Sure! Code reusability refers to the practice of using existing code in new applications or projects, which helps save time and effort. On the other hand, code duplication occurs when the same code is copied and pasted in multiple places, leading to maintenance challenges and potential errors.

Can you give me an example of each?

Absolutely! An example of code reusability is creating a function that calculates the area of a rectangle, which can be called whenever needed. Code duplication would be writing the same area calculation in multiple places without using a function.

Why is code reusability important?

Code reusability is important because it reduces redundancy, makes code easier to maintain, and enhances collaboration among developers. It also speeds up the development process since you can leverage existing solutions.

What are some best practices for achieving code reusability?

Some best practices include using functions and classes, following the DRY (Don't Repeat Yourself) principle, and creating libraries or modules that can be shared across projects.
