angular.scope.$become

Description

Modifies the scope to act like an instance of the given class by:

• copying the class's prototype methods
• applying the class's initialization function to the scope instance (without using the new operator)

That makes the scope be a this for the given class's methods — effectively an instance of the given class with additional (scope) stuff. A scope can later $become another class.

$become gets used to make the current scope act like an instance of a controller class. This allows for use of a controller class in two ways.

• as an ordinary JavaScript class for standalone testing, instantiated using the new operator, with no attached view.
• as a controller for an angular model stored in a scope, "instantiated" by scope.$become(ControllerClass).

Either way, the controller's methods refer to the model variables like this.name. When stored in a scope, the model supports data binding. When bound to a view, {{name}} in the HTML template refers to the same variable.
