Refactoring involves restructuring existing code without changing its external behavior through small, behavior-preserving transformations. It improves code readability, maintainability, and quality over time. Refactoring is useful for prototyping with unclear specs, gaining project overview on large codebases, and improving poorly designed code. It can save significant time versus rewriting from scratch by allowing work to progress iteratively while preserving existing functionality and APIs. Examples demonstrate how refactoring authentication and database code improved structure without affecting existing features or tests.
