    // preventing against multiple instantiations

حال می خواهم برای قسمتهای زیر

  var upperCase = new RegExp('[A-Z]');

            var lowerCase = new RegExp('[a-z]');

            var numbers = new RegExp('[0-9]');

            var specialchars = new RegExp('([!,%,&,@,#,$,^,*,?,_,~])');

علاوه بر کلمات انگلیسی حروف فارس هم چک شود
کد را باید چگونه تغییر بدهم
باتشکر
