Code Refactoring
Refactoring Principles
When to Refactor
- Before adding new features (make change easy, then make easy change)
- After getting tests passing (red-green-refactor)
- When you see code smells
- During code review feedback
When NOT to Refactor
- Without tests covering the code
- Under tight deadlines with no safety net
- Code that will be replaced soon
- When you don't understand what the code does
