It is a known best practice to avoid using global variables when possible. Therefore, Angular provides you with a valid 'angular' way option to get the window object inside your code as a service. It is incredibly useful for tests to have that option.

Mainly for testability purpose as stated in Doc

While window is globally available in JavaScript, it causes testability problems, because it is a global variable. In angular we always refer to it through the $window service, so it may be overridden, removed or mocked for testing.
