Prefer RegExp.exec when regular-expression match details are consumed

String.match changes its result shape for global patterns and places matching behavior on the input string.
Instead, you SHOULD call RegExp.exec for a non-global pattern when consuming one match record.

Global patterns remain with String.match because they collect every match rather than one match record.
