The pattern parameter consists of regular expression language elements that symbolically describe the string to match. I had to write quite of code to get matches with their indexes like that: { '22': 'john.doe@example.com', '47': 'person2@lodash.ru' } and lodash function that will return similar structure will be good for me.
