Lat/Lng Object Literal

  • This example demonstrates centering a map and adding a marker using aLatLng object literal instead of agoogle.maps.LatLng object.

  • LatLng object literals offer a convenient way to specify latitude and longitude coordinates and can often replacegoogle.maps.LatLng objects.

  • The sample code showcases how to create a map, add a marker with aLatLng literal, and display an info window with the marker's position.

  • This approach simplifies the process of adding coordinates to your map, improving code readability.

This example demonstrates using aLatLng object literal instead ofagoogle.maps.LatLng object, to center the map and add a marker.LatLng object literals are a convenient way to add aLatLng coordinate and, in most cases, can be used in place of agoogle.maps.LatLng object.
