FAQ
Which regex flavor is supported?
JavaScript / ECMAScript regex. This differs from PCRE (Perl) in look-around and named groups syntax. For server-side patterns, double-check on your server runtime.
Why is the g flag forced on?
The tester always finds all matches. matchAll with g is the cleanest way to enumerate them without lastIndex pitfalls.
