I don't know much about browser-side javascript, but unless they're doing something really weird in the event loop I believe the comments // this might execute before the $.get() above is complete and // something additional to execute upon success, which might, or might not, // have fired by now. With $.ajax deferreds built-in, it doesn't matter. are misleading. In fact, the first comment should read "this will execute before the $.get() above is complete" and the second one should read "which will not have fired yet". Someone please correct me if I'm wrong on this.
