How to Approach Refactoring
summary
Refactoring is a disciplined, incremental process that improves internal design without changing behavior: write tests or other feedback first, rely on automated test, then take many small commits that each pass before proceeding. Focus on removing code, avoiding clever shortcuts, keeping functions small and cohesive, eliminating duplication and unnecessary dependencies, and making intent clear so the reader understands in seconds. Do refactors before or after bug fixes but not during them, pair for safety, and follow the mantra make it work make it better real soon.
