New styles, like John Papa's AngularJS Styleguide, are suggesting that we shouldn't be using $scope to save current page's properties at all. Instead we should use the controllerAs with vm approach where the view binds to the controller object itself. Then use a capture variable for this when using the controllerAs syntax. Choose a consistent variable name such as vm, which stands for ViewModel.

You will still need the $scope for its watching capabilities though.
