What it's for: Test regular expressions against sample text with live match highlighting and capture groups. Debug patterns before shipping them. Instant.
What trips people up: Why does my pattern match nothing? Common causes are an unescaped special character, a missing global flag when you expect several matches, or anchors that assume single-line input.
