I am trying to display current date in my application using moment JavaScript library, I am getting referenceerror message.

I have the moment.js file under my scripts folder and my Bookshow.js file under resource folder.

I also referred to this link but still facing the reference issue - AngularJs and moment.js not working

Error Details

book.service('ApplDate', ['$scope', '$http', '$filter', function($scope, $http, $filter) {

$scope.today = moment();
console.log("today date " + today.format('MM/DD/YYYY'));
$scope.applDate = today.format('MM/DD/YYYY');
}]);
