A simpler (and smaller) rewrite of Google Android's libphonenumber library in javascript

    }
  }

  var possibleCountries = metadata.getCountryCodesForCallingCode(callingCode);

  if (!possibleCountries) {
    return;
  } // If there's just one country corresponding to the country code,
  // then just return it, without further phone number digits validation.


  if (possibleCountries.length === 1) {
    return possibleCountries[0];
  }
