Code Golf: The zen of writing bad code II
summary
Walks through concrete PowerShell code golf: using the code.golf web runner (PowerShell 7), shaving whitespace and aliases, replacing if chains with ternary and null‑coalescing, and abusing scriptblocks, string multiplication, deconstruction, regex match and hash lookups. Shows a FizzBuzz reduction 287→42 characters and an arrows solution trimmed to ~155 (leaderboard at 66), plus a 12‑Days version at ~424 — all validated on the site and iterated until the output matches the tests.
