How to reverse an array in angular js without creating a filter

I am having an array in controller as follows

function FooController($scope) {
    $scope.items = ["a","b","c"];
}

I used ng-repeat to show the data in items,

<div ng-app>
    <div ng-controller="FooController">
        <ul ng-repeat="item in items">
            <li>{{item}}</li>
        </ul>
    </div>
</div>

I got the result as a,b,c order. I want to show it in reverse order. that means c,b,a without changing its order in the controller or without creating a filter. How to do that? Check this link
