We are going to learn how to manage simple states within our controller. We are going to learn how to toggle between the editing and creating bookmark states and how to sequence those interactions in the controller.

I'm wondering why you are declaring functions and then attaching them to the scope. Can't this be accomplishing in one step?

For example, you have the following:

function startCreating() { $scope.isCreating = true; } $scope.startCreating = startCreating;

Can this be written as follows?

$scope.startCreating = function () { $scope.isCreating = true; }

Couldn't we achieve the same result with just two functions?

function setCurrentAction(action) {
	$scope.currentAction = 'action';

function cancelCurrentAction() {
	$scope.currentAction = null;

Doing so we could also re-use quickly implement additional actions.

~Minute 6:15 "it's actually a property": Why are you emphasizing using ng-if="xxx" with no brackets here and using ng-if="xxx()" (with brackets) every where else?
