Exploring the Depths of Scope Hierarchy in AngularJS

Upon inspecting the _proto__ property of an object I created, it is evident that it has been inherited from Object.

Further exploration reveals that when a new object is created and inherits the obj object, the inheritance structure appears as depicted in this image https://i.stack.imgur.com/HoSX4.png

It can be observed that the object obj1 is inheriting from obj and obj itself is inherited from Object, which serves as the global object.

Curiously, when analyzing the console debug output, both obj and obj1 are identified as Object. However, when examining the $scope within AngularJS, a different result is obtained

Why does $scope return 'b' instead of Object, especially considering the previous objects? What sets AngularJS apart in this scenario?

UPDATE 1

Noticeably, while creating an object of a constructor in JavaScript, the constructor function name is displayed, as shown in this image

However, in the case of $scope, no constructor function is visible. This discrepancy raises questions - what could be causing this difference? Your insights are welcome.

Answer №1

The reason for this issue is that you are trying to troubleshoot a minified application.

When dealing with Angular, $scope represents an instance of the internal Scope or ChildScope class.

Within a minified version of Angular, this class may be referenced as something like b.

Answer №2

When examining an object in the console, it is identified by the class name of that object, as shown below:

function User() {}
var u = new User();

https://i.stack.imgur.com/M3Rpt.png

In your scenario, instead of function User() {}, in the compressed version of the code it appears like this: function x() {} and new x() is used instead of new User()
