AHA Programming
summary
A concrete case for Avoid Hasty Abstractions that live codes a real refactor: a getDisplayName function moved from three duplicated sites into one, then bloated with options like includeHonorific, includeUserName and firstInitial, with unit tests and VS Code demo using cocaJas console output. The claim is: prefer short-term duplication and inline copies, then extract a cleaner abstraction per Sandi Metz’s “fastest way back” approach. Practical, tool-backed, example-heavy.
