The Power of $q
summary
Shows that replacing callbacks with promises via $q actually makes code parallelizable, composable and dynamic, demonstrates $q.all for parallel results, the spread helper for positional args, and $q.when plus a cached-P trick that prevents duplicate HTTP requests. Explains deferred.resolve/reject and deferred.notify for progress, points out $q schedules callbacks to the next digest loop, and describes promise-based request/response interceptors; mentions Nutella and bacon in the uploader note.
