ng-inspect helps you access properties of the element's scope when an element is selected using the Element Inspector or the Elements tab in the Developer Toolbar in an Angular JS aplication.
This extension will provide access to scope, isolateScope[if the scope is isolated], rootScope, jQuery element and its events[if jQuery is included in the page].
These properties are made available to the Global/Window object via $s for scope, $is for isolateScope, $rs for rootScope, $el for jQuery element and $events for the events associated with the jQuery element.
Services/Factories/Constants can be tested/verified using $get function.
$count function prints number of Scopes, isolateScopes, listeners and watchers.
Hope you find this useful!
