Refactoring Is Not Just Clickbait
summary
Claim: refactoring is a design process not a shortcut key, it preserves behavior while improving developmental quality and often succeeds only when intent and technique match available tools. Examples: Java Streams and TreeSet replace manual loops, a table driven Roman numeral refactor simplifies and works, Python assertions stand in for a test framework, Visual Studio can break a 1,500‑line method. Surprises: legacy code can appear in about five minutes and automated tools help but don’t replace judgment. Common moves are refactoring preserves semantics, extract method and rename, and pass the value not the provider.
