Frequently asked questions
Which regex flavor does it use?
It uses the JavaScript (ECMAScript) regular-expression engine — the same one in browsers and Node.js — so results match what your JavaScript code will do.
What do the flags do?
g matches all occurrences, i ignores case, m makes ^ and $ match each line, s lets the dot match newlines, and u enables full Unicode handling.
