Getting user region and city with Yandex.Maps API

yandex-maps-example.js

ymaps.ready(function () {
	ymaps.geolocation.get({ provider: 'yandex' }).then(function(result) {
	  
		var data = result.geoObjects.get(0).properties.get('metaDataProperty').GeocoderMetaData;
		var administrativeAreaName = data.AddressDetails.Country.AdministrativeArea.AdministrativeAreaName; // region
		
		if ('SubAdministrativeArea' in data.AddressDetails.Country.AdministrativeArea) {
			var localityName = data.AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.LocalityName; // city
		} else {
			var localityName = data.AddressDetails.Country.AdministrativeArea.Locality.LocalityName; // city
		}

	});

});

я бы еще добавил проверку

    var data =result.geoObjects.get(0).properties.get('metaDataProperty').GeocoderMetaData.AddressDetails.Country.AdministrativeArea;
            var city = '';
            if ('SubAdministrativeArea' in data) {
              city = data.SubAdministrativeArea.Locality.LocalityName; // city
            } else if(data.Locality) {
              city = data.Locality.LocalityName;
            } else {
              city = data.AdministrativeAreaName;
            }

она нужна например для Москвы, ее моно получить только так data.AdministrativeAreaName;
