ng-inspect for AngularJS is a Chrome extension developed by Vinay Kaparthi. This free tool is designed to assist developers in debugging AngularJS applications. With ng-inspect, the elements panel in devtools is extended to display scope properties, making it easier to access and analyze the data within an element's scope.

When using the Element Inspector or the Elements tab in the Developer Toolbar, ng-inspect provides access to various properties of the selected element's scope. These properties include scope, isolateScope (if the scope is isolated), rootScope, jQuery element, and its associated events (if jQuery is included on the page). These properties are conveniently made available to the Global/Window object via $s, $is, $rs, $el, and $events respectively.

In addition to scope properties, ng-inspect also offers the ability to test and verify Services, Factories, and Constants using the $get function. Furthermore, the $count function can be used to print the number of Scopes, isolateScopes, listeners, and watchers, providing valuable insights into the application's structure.

Overall, ng-inspect for AngularJS is a useful tool for developers working with AngularJS applications, offering enhanced debugging capabilities and easy access to scope properties.
