I don't understand the use of $inject in controllers

Question

I am totally confused about inject in Angular. I do not know where to use it and why. Is it only used with factory as described here?

myController.$inject =          


        

Answer 1

To complement @mark answer, it is important to note that using the $inject method in the style of:

MyController.$inject = ['$scope', 'notify'];

allows you to add injection dependencies when building providers which are the only angular recipes that don't allow 'friendly' annotation style i.e.:

.controller('MyController', ['$scope', 'notify',... 

dependencies to be declared.
