If you have many many points, you could store them in two arrays (to
minimise the number of objects being allocated), one for lat, one for lng.
Then iterate through and create LatLng objects as desired.
var lat = [47.38154, 47.3815, 47.38147, 47.3814, 47.38138, 47.3813];
var lng = [-93.70881, -93.70879, -93.70879, -93.70898, -93.70908,
-93.70914];
var latlng = [];
for (var i = 0, ii = lat.length; i < ii; i++) {
latlng.push(new google.maps.LatLng(lat[i], lng[i]));
}
