The separation of concerns in AngularJS is achieved by using a service. A Service is a singleton javascript object and gets instantiated only once during an applications lifetime. Services provide some very useful methods essential to implement some powerful angular concepts.
For example $http service provides methods like GET, POST, PUT and DELETE which help to contact the server and help perform CRUD operations. Angular also provides the ability to create custom services. A service can be created in the below fashion in an angular application :
angular.module('myModule', []).factory('serviceId', function() {
var shinyNewServiceInstance;
return shinyNewServiceInstance;
});
