google.maps.LatLngLiteral interface
Object literals are accepted in place of LatLng objects, as a convenience, in many places. These are converted to LatLng objects when the Maps API encounters them.
Examples:
map.setCenter({lat: -34, lng: 151});
new google.maps.Marker({position: {lat: -34, lng: 151}, map: map});
LatLng object literals are not supported in the Geometry library.
Properties
Type: number
Latitude in degrees. Values will be clamped to the range [-90, 90]. This means that if the value specified is less than -90, it will be set to -90. And if the value is greater than 90, it will be set to 90.
Type: number
Longitude in degrees. Values outside the range [-180, 180] will be wrapped so that they fall within the range. For example, a value of -190 will be converted to 170. A value of 190 will be converted to -170. This reflects the fact that longitudes wrap around the globe.
