ince it is something you will probably do quite often. You should make
add a "clear" function to the MVCArray.
google.maps.MVCArray.prototype.clear = function (){
// work backward should be faster
for(var i=this.getLength(); i>0; this.removeAt(--i)) {};
}
.....
myMvcArray.clear();
myMvcArray.push(new google.maps.LatLng(40.6, -73.9));
myMvcArray.push(new google.maps.LatLng(53.4,117.0)); // will show a
line from NewYork to Siberia
Pop is more expensive operation, then removeAt.
I also get the length once.
You have to watch out for the order/index which you delete or else
you have a half empty array.
try "myMvcArray.removeAt(0);" or go backward
