I am baffled by this one. In the angular api and on github there is a merge function which does a deep merge on two objects, unlike extend() which does a shallow copy.
I use google's cdn for angular, and call angular.extend('param') works, but calling angular.merge('param') gives undefined function. Comparing the angular.js from google and the one from angular them selves, merge does exist on the angular one, but not in google.
Any ideas, or someone else with this problem. Could I let google know somehow?
