Little Snippets
summary
Real examples from Ruby and ActiveRecord show concrete swaps that save time or bugs: use sort...last → max instead of sorting, prefer String#include and Regexp#match (the latter is about 2–3x faster and has no regex side‑effects) instead of =~, use \A and \z for exact anchors (not ^/$), prefer require_relative over File.expand_path, use $stdout not STDOUT for testable output, remove redundant self, name units like threshold_in_seconds, and favor concise, specific APIs for clearer intent and better performance.
