Refactoring Is Not Just Clickbait
summary
Argues that refactoring is a continuous design activity not just IDE shortcuts, with automated tools handling many renames and extract methods but leaving a stubborn 5% of hard problems (95% solved by tooling). Advocates committing small, focused changes — many refactors then one feature (refactor-driven commits (29 refactors 1 feature)) — and preserving observable behavior while improving maintainability. Shows concrete examples: reversing a stack representation, turning Roman‑numeral control flow into a lookup table, and collapsing sort + dedupe into a data structure; tests and IDE refactor tools are used but deep refactors remain manual.
