Google Maps API v3 - How to clear overlays?

Question

In Google Maps API v2, I was using map.clearOverlays() to remove the marker and draw them again.

How can I do that using Google Maps API v3 ?

clearOverlays() in V3

There is no clearOverlays() in API v3. Some practices have been presented. I think this is the simpliest so far.

Push all the overlays in an array when created (as usual). Following code will clear both map and the array:

while(overlays[0])
{
  overlays.pop().setMap(null);
}

pop() method of an array removes the last element of an array, and returns that element. 'while' keeps that happening as long as there are elements in the array. When overlays[0] does not exist anymore, the mission is completed and code will proceed.
