The zen of writing bad code
summary
This walks through concrete PowerShell code‑golf reductions: actual solutions that run on the code.golf validator and appear on the leaderboard. It uses PowerShell 7 operators (null‑coalescing, ++), shadow aliases like date/get-date, pipeline property expansion and deconstruction, and counts characters while trimming whitespace. Examples hit a 16‑character day‑of‑week solution and a 29‑character Fibonacci vs a 27‑character best, with working outputs and diffs from the site so every tight rewrite is verified.
