service guide doesnt work

[MrOutput]

I am not sure if the angular team had mixed ideas about services and factories. But the code and ideas mentioned in the services section don't add up, not even on angular's site. If service registration takes a constructor function as the second argument, and its suppose to be invoked as a constructor would, with the new keyword, then why can't I treat it as a true constructor passing in parameters?

Service

(function () {
    angular
        .module("App")
        .service("Person", Person);

    //angular wants my parameters to be injectables.
    function Person(name, age) {
        this.name = name;
        this.age = age;
    }
})();

Controller

(function () {
    angular
        .module("App")
        .controller("DemoController", DemoController);

    DemoController.$inject = ["Person"];

    function DemoController(Person) {
        var a = new Person("rafael", 22);// ERROR

        var Demo = this;

        Demo.title = "Demo";
    }
})();

Use factory instead of service
Angular is singleton for factory and services...

(function() {

    angular
        .module('App')
        .factory('servicePerson', servicePerson);

    function servicePerson() {
        function Person(name, age) {
            this.name = name;
            this.age = age;
        }

        Person.prototype.alert = function() {
          alert('Name:' + this.name +' Age:'+ this.age);
        }

        var service = {
            newPerson : newPerson
        }

        return service;

        function newPerson(name, age){
            return new Person(name, age); 
        }
    }
}) ();

In controller

(function() {

    angular
        .module('App')
        .controller('DemoController', DemoController);

    DemoController.$inject = ['servicePerson'];

    function DemoController(servicePerson) {
        var a =  servicePerson.newPerson('rafael', 22);
        a.alert();
        var Demo = this;

        Demo.title = 'Demo';
    }
}) ();
