Code Snippet: Formatting a social security number

@param

nothing too crazy, but might be handy if anyone out there needs to do this (as I did).

 /**   * Formats raw input to ###-##-#### format   * @param {String} raw Source string to format   * @return {String} The formatted string   */  PMDUtils.FormatSsn = function PMDUtils_formatSsn(raw)  {      Guard.NotNullOrEmpty(raw, 'A valid ssn string is required');            var newString = [];      var currCharCode;      var delimiter = '-';            //  Copy only the numeric characters into a clean buffer      for(var i = 0, len = raw.length, j = 0; i < len ; i++)      {          currCharCode = raw.charCodeAt(i);                    // Character codes for ints 1 - 9 are 48 - 57          if (j < 9 && currCharCode >= 48  && currCharCode <= 57)          {              newString.push(raw.charAt(i));              if(j === 2 || j === 4)              {                  newString.push(delimiter);              }                            j++;          }         }        return newString.join('');  }
