Well-known Built-in Services
$http - Allows promise-based access to HTTP requests. Promises are covered in subsequent topics.

$resource - Provides a higher-level abstraction for accessing REST-style services.

$document - A jQuery (lite)-wrapped reference to window.document.

$window - Is a jQuery (lite)-wrapped reference to window.

$timeout - A wrapped version of window.setTimeout. In tests, you can use $timeout.flush() to synchronously execute all scheduled timeouts.

$parse - Parses Angular expressions (eg: for binding with ng-model or similar) and provides accessor functions.

$cacheFactory - Used by other services whenever a scoped cache of elements is needed.

$filter - Provides programmatic access to a filter function.


Scope life cycle is called dirty checking

$apply is at module level
$digest works at controller level
$watch works at variable level

$scope is an object accessible from current component e.g Controller, Service.

$rootscope refers to an object accessible from everywhere of the application.



AngularJS Life Cycle
