Google Maps API v3: How to remove all markers?

Question

In Google Maps API v2, if I wanted to remove all the map markers, I could simply do:

map.clearOverlays();

How do I do this in Google Maps A

Answer 1

This is the method Google themselves use in at least one sample:

var markers = [];

// Clear out the old markers.
markers.forEach(function(marker) {
  marker.setMap(null);
});
markers = [];

Check Google sample for complete code example:
