阅读更多关于 AngularJS : When to use service instead of factory

Please bear with me here. I know there are other answers such as: AngularJS: Service vs provider vs factory However I still can't figure out when you'd use service over factory. From what I can tell factory is commonly used to create "common" functions that can be called by multiple Controllers: Creating common controller functions The Angular docs seem to prefer factory over service.

This question already has an answer here: AngularJS: Service vs provider vs factory 30 answers EDIT Jan 2016: Since this still gets attention. Since asking this I've completed a few AngularJS projects, and for those I mostly used factory , built up an object and returned the object at the end. My statements below are still true, however.
