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 uses window.setTimeout() to place markers on the map consecutively rather than all at once when a Drop Markers button is clicked.
Read the documentation.
