AngularJS/Javascript assigning a key to a variable syntax

Question

Since i put a unique key in my Local Storage, I am not so sure if i have to reference it in the view

//Model

$localStorage['uniqueKey'] =[{id:1, name:"foo"}, {id:2, name:"bar"}]

// Controller

$scope.users = $localStorage['uniqueKey'];

//View --> do I have to refer to the unique Key?? or this is okay?????????

<li ng-repeat="user in users">
{{user.name}}
</li>

$scope.users = $localStorage.['uniqueKey']; 
                            ^^ syntax error: dot should not be here

//This should be:

$scope.users = $localStorage['uniqueKey'];
//or
$scope.users = $localStorage.uniqueKey;
//or
$scope.users = $localStorage.get("uniqueKey");

Correct usage. Storing objects in localStorage:

$localStorage.uniqueKey = angular.toJson([{id:1, name:"foo"}, {id:2, name:"bar"}]);

$scope.users = angular.fromJson($localStorage.uniqueKey);

You can use the angular.toJson() to convert an object to a string, and angular.fromJson to reverse it. Demo

You not can storing objects into localStorage, here just are stored strings. look this answer

I don't think you got the question... so let's say i did this $scope.users = $localStorage['uniqueKey']; in my view.... DO I HAVE TO REFERENCE the 'uniqueKey'?? <li ng-repeat="user in users"> {{user.name}} </li>

if you work with localStorage you must first convert the object to a string and then reverse it. Demo
