New to Angular - Computed Variables

Question

I am moving to Angular from Knockout, and I have a few issues. I\'m assuming that I must be doing something a non-angular type of way.

I'm new to AngularJS but I think that $parse could be used:

http://docs.angularjs.org/api/ng/service/$parse

This is interesting if you have the expression as a string. You can use a path of properties and that string can be generated dynamically. This works if you don't know the expression at compile time, a lot like eval() but probably a lot faster and maybe more secure(?).

Here's an example:

function Ctrl($scope,$parse) {
  var expression = 'model.val1 + model.val2';//could be dynamically created
  $scope.model = {
    val1: 0,
    val2: 0,
    total: function() { 
        return ($parse(expression))($scope); 
    }
  };
}
