Create AngularJS application that allows users to maintain a collection of items. The application should display the current total number of items, and this count should automatically update as items are added or removed. Users should be able to add items to the collection and remove them as needed.
Program:-
<!DOCTYPE html>

<script type="text/javascript"

$scope.addItem=function()

if($scope.itemList.indexOf($scope.newItem)==-1)
{
$scope.itemList.push($scope.newItem)
}

}
}

}
}
$scope.removeItem=function(item)
{
var yes=confirm("Are you sure you want to delete "+item)
if(yes==true)
{
var index=$scope.itemList.indexOf(item)
$scope.itemList.splice(index,1)
