Using the value method Using the constant method Further in the post we will talk about options to create the service. Above we have created the calculator service using the service method.

If we use factory method to register the service it returns the value after execution of the service function. It can return any value like primitive value, function or object.

So service method returns the function object whereas factory method can return any kind of value. In further post we will talk about other ways of creating service.


Now let us work on a full working example of using service in an angular app. With the assumption that REST based service is already in place to retrieve the students and add a student, we will write the angular application. There are two methods in the service. Once service is created, let us create the controller which will use the service to perform the operations.
