I just saw this section today.

Excerpt, and later, after the actual operation is complete, all the code will be

Sometimes, it might is interesting to create configurable services. They is called providers, and despite being more complex to create, they can configured before
Being available to is injected inside other components.
While the factory works by returning a object and the service with the constructor function, the provider relies on the $ Get function to expose its
Behavior. This is the everything returned by this function becomes available through the dependency injection.
In the following code, we refactored our service to being implemented by a provider. Inside the $get function, the Calculateticket method is being returned and would be
Accessible externally.

Parking.provider ("Parkingservice",function(parkingconfig) {var_parkingrate =parkingconfig.parkingrate;var_calculateticket =function(car) {varDeparthour =NewDate (). getHours ();varEntrancehour =car.entrance.getHours ();varParkingperiod =Departhour–entrancehour;varParkingprice = Parkingperiod *_parkingrate;return{period:parkingperiod,price:parkingprice};}; This. setparkingrate =function(rate) {_parkingrate=Rate ;};This . $get = function () {return {calculateticket: _calculateticket};};});
