An Angular scope is a JavaScript object with additional APIs useful for watching property changes,
Angular scope is the model in Model-View-Controller paradigm. Instances of scope serve as the
context within which all {@link dev_guide.expressions expressions} get evaluated.

You can think of Angular scope objects as the medium through which the model, view, and controller
communicate. Scopes are linked during the compilation process with the view. This linkage provides
the contexts in which Angular creates data-bindings between the model and the view.

In addition to providing the context in which data is evaluated, Angular scope objects watch for

model changes. The scope objects also notify all components interested in any model changes (for
example, functions registered through {@link api/angular.scope.$watch $watch}, bindings created by
{@link api/angular.directive.ng:bind ng:bind}, or HTML input elements).

* Link the model, controller and view template together.
* Provide the mechanism to watch for model changes ({@link api/angular.scope.$watch}).
* Notify interested components when the model changes ({@link api/angular.scope.$eval}).
* Provide the context in which expressions are evaluated.
