AngularJs Service, Factories and Providers

 Service in AngularJS

AngularJs Service, Factories and providers are all injectable types.

An AngularJs service encapsulates specific business logic & exposes an API to be used by other components to invoke this logic.

e.g. $timeout service executes function after specifies interval. $http service encapsulates the logic required to interact with REST backbends.

AngularJS service is always Singleton.

Service is registered using service function of angular.module().

The Second argument to service() is a constructor function to inject the service.
