>Many would not even see the problem here, and just as children don't know cars can hurt, juniors don't know just how destructive this anti-pattern can be to performance, separation of concerns and long term code base maintenance.

Yup, I don't get it. I guess not only am I eternally doomed to be a junior dev but also am being compared to a child, a monkey typing at a typewriter, but also someone who doesn't know JS at all. Feels good man.

Other than some horribly obtuse undefined checking, there's no explanation of what the problem is. The argument seems to be that the controller depends on $scope. I... I thought that was the point. From the first line of documentation on controllers:

>In Angular, a Controller is a JavaScript constructor function that is used to augment the Angular Scope.

If the idea is that this is a bad habit to bring elsewhere, fine. Some more explanation would be nice, but whatever. But the implication is that this is a trap within the context of Angular dev itself.
