JavaScript | Angular | Controller As Syntax: Cannot Use `this`

Question

Cannot Use ControllerAs this

Can anyone explain the following scenario to me, please?

Works

ng-controller=\"Parent as thus\"         


        

Answer 1

You are cannot use this as the instance name. this is a reserved keyword.

It would be the equivalent of doing:

var this = new Controller();

You can see that is wrong. It should be something like:

var ctrl = new Controller();

This is essentially what angularJs does behind the scenes when you do controllerAs="Controller as ctrl"
