Requirements to try out things described below:
Super large numbers as LatLng’s
Open this page from Google’s example. In firebug’s console, execute the following code:
map.setCenter(new GLatLng(1e100, 1e100));
Setting super large numbers as latitude and longitude like this always makes my Firefox 18.104.22.168 in Windows XP hang.
I don’t know why Google didn’t restrict the range of the numbers, and what computation it did to consume so much CPU time. It should ignore such numbers after a simple judgment.
Strings as zoom parameters
In the same page, execute this piece of code:
var zoom = '16'; map.setZoom(zoom);
a = 2 * '3'; // a = 6
It will be converted to number when needed. Of course, it’s good to perform strict type checking. But it’ll be better if the API threw an exception instead of being silent.
