Is there a way to associate an empty array with an object property so it can be accessed later using dot notation?

var AJAX_Utils_AddressBook = {
contacts: null
};
var contact = [];
AJAX_Utils_AddressBook.contacts = contact;
console.log(AJAX_Utils_AddressBook.contacts.contact.length);
Encountered this error message:
AJAX_Utils_AddressBook.contacts.contact is undefined
No objects are in contact with each other.
To retrieve the information, use this code:
console.log(AJAX_Utils_AddressBook.contacts.length);
To make your code functional, it should be written like this:
var contact = [];
AJAX_Utils_AddressBook.contacts = { contact: contact };
