Regex flags
What this is
g global, i ignore case, m ^ $ per line, s dotAll, u Unicode, y sticky, d capture indices, v unicodeSets. This tester exposes all of them. Flavor pages on regex101 that claim PCRE flags (x, J) do not apply here — this engine is JavaScript.
FAQ
- Why no x (extended)?
- PCRE-only. JavaScript has no insignificant-whitespace flag. Use comments outside the pattern.
