$window Service In Angular Js
AngularJs includes $window service which refers to the browser window object.
In the JavaScript, window is a global object which includes many built-in methods like alert(), prompt() etc.
The $window service is a wrapper around window object, so that it will be easy to override, remove or mocked for testing. It is recommended to use $window service in AngularJS instead of global window object directly.
Example: $window
