Count child nodes in Firebase

I am creating an online ticket system where the tickets are pushed and displayed from Firebase. Is there a way to keep track of how many tickets there are?

I actually figured out the answer myself later on.

  var ref = new Firebase("https://xxxxxxx/");
  var ticketRef = ref.child("tickets");
  var count = 0;
  ticketRef.on("child_added", function(snapshot) {
   var newTicket = snapshot.val();
   count++;
  });

EDIT Thanks to Frank Van Puffelen, it seems that using firebase's transaction function would be a better course. Sample code
