While taking Angular's complimentary online course, I came across the following code snippet:
app.controller('GalleryController', function(){
this.current = 0;
this.setCurrent = function(imageNumber){
this.current = imageNumber || 0;
};
});
It is worth noting that typically the $scope is passed as an argument to the controller. Is it actually necessary in this case?
Take a look at the updated "controller as" syntax by visiting this link: https://docs.angularjs.org/api/ng/directive/ngController
It all comes down to whether you plan on utilizing it within your controller or not. If $scope is not being used in your controller, there is no need to pass it as an argument.
