As of February 21st, 2024 (v3.56), google.maps.Marker is deprecated. We encourage you to transition to the new google.maps.marker.AdvancedMarkerElement class. Advanced markers provide substantial improvements over the legacy google.maps.Marker class. The minimum version of the Maps JavaScript API with google.maps.marker.AdvancedMarkerElement is 3.53.2. At this time, google.maps.Marker is not scheduled to be discontinued.
This example creates a map where each click by the user creates a marker. Click the buttons to hide or delete all of those markers.
Read the documentation.
