Today I was going to the Google Maps API documentation and after using it for a while, my eye was caught by this:

It’s maybe a bit difficult to read from the above image, but it says:
The Google Maps API is now integrated with the Google AJAX API loader…
I couldn’t remember seeing this before, so besides clicking on the link, I googled “Google AJAX API loader”. I found out it’s a very new way of using multiple Google javascript APIs on the same page.
The main purpose for the loader is to unify namespaces across the different APIs on one page and to have only one script tag instead of separate script tags for each of the APIs you wanna use on your page.
