Improve code structure while preserving behavior. Refactoring is required to clean up code smells, restructure a class or function, or improve overall quality without changing external behavior.
Describe the exact code area to refactor and the behavior to preserve, then start with small, test-guided changes and verify behavior after each step.

To refactor code without changing behavior, make small, incremental changes and keep the code working after each step. Never change behavior in the same commit, and use test-driven development to verify functionality throughout the restructuring process.
Common refactoring techniques include Extract Method, Extract Class, Replace Conditional with Polymorphism, and Introduce Parameter Object. These patterns improve readability and maintainability by restructuring code smells without modifying external functionality.
You need to refactor code when a project has bloated classes, complex switch logic, or code smells. Refactoring cleans up classes or functions and restructures modules to improve overall quality while preserving the existing external behavior.
Yes, you need to write tests first before refactoring code. Test-driven development is a core requirement, ensuring you verify behavior after each small, incremental change to guarantee the restructuring does not alter external functionality.
The best way to start refactoring safely is to describe the exact code area to refactor and the behavior to preserve. Then, begin with small, test-guided changes and verify the behavior after each incremental step to ensure continuous functionality.
