When should I refactor my code?

When should I refactor my code?

Refactoring is essential when your code becomes difficult to understand, maintain, or extend. It's often a good idea to refactor when you notice code smells, such as duplicated code or overly complex functions.

What are some common signs that my code needs refactoring?

Common signs include duplicated code, long methods, large classes, and a lack of unit tests. If you find yourself avoiding changes due to complexity, it's time to refactor.

Is there a specific time in the development cycle when I should refactor?

It's best to refactor during regular development cycles, especially after adding new features or fixing bugs. This keeps the codebase clean and manageable.

Can refactoring improve performance?

Yes, refactoring can improve performance by optimizing algorithms and reducing resource consumption, but the primary goal is to enhance code quality.

How do I approach refactoring without breaking existing functionality?

Start by writing unit tests to cover existing functionality. Then, refactor in small increments, running tests frequently to ensure nothing breaks.
