What are the best practices for applying the DRY principle in software development?

What are the best practices for applying the DRY principle in software development?

The DRY principle, or 'Don't Repeat Yourself', emphasizes reducing repetition in code. Best practices include using functions, classes, and modules to encapsulate reusable code.

Can you give me an example of how to implement this in a project?

Sure! For instance, if you have a function that calculates tax, instead of writing it in multiple places, create a single function and call it wherever needed.

What tools can help enforce the DRY principle?

Tools like linters and code analysis tools can help identify duplicate code. Additionally, using version control systems can help manage code changes effectively.

Are there any common pitfalls to avoid when applying the DRY principle?

Yes, one common pitfall is over-abstraction, where you create too many layers of abstraction, making the code harder to understand. It's important to balance reusability with clarity.
