title: Angular JS - Is there any usecase for using services and factories together in same module
body: <p>I am very newbie to AngularJS and sorry if it is a basic question. </p>
  
  <p>I know that the services and factories are used for doing almost the same thing. They are used to get the external data.</p>
  
  <p>But, is there any use case where we should use both in the same angular module? Just curious, as I was going through one of the github projects and realized they were using both services and factories for the same module. What is the advantage of doing it?</p>
