The substring after the delimiter (may be empty string), or on_missing.
A delimiter at the end returns an empty string, not on_missing; an empty delimiter
returns all of s. Useful for removing a path, field, or protocol prefix.
Regex flags are preserved; matching starts at zero without reading or changing the
caller's lastIndex. Global regexes use the first match; sticky regexes must match at zero.
Returns the substring after the first occurrence of the delimiter.
