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 =

The way you should use $inject is:

function ApplicationController($scope){
    $scope.greet = "Foo is Not Great!5";
}

ApplicationController.$inject = ['$scope','$ionic'];

app.controller('ApplicationController', ApplicationController);

We need to this as to protect the code from uglifying or minimization.

function(firstName,lastName) may get turned into function(n,m).

So for AngularJS it will break the code because $scope can be replaced by 's'. This is because without the $ sign the angularJS won't be able to recognize the code.
