Hello there let's assume we have some string '20090102' which is date in ISO format. And we want to match/parse it against regexp. I wonder what method of writing regexp would be more efficient: /(\d\d\d\d)(\d\d)(\d\d)/ or /(\d{4})(\d{2})(\d{2})/ so mainly question in what is better: \d\d\d\d or \d{4} ? :) Thanks
