function list() {
    var contactsLength = contacts.length;
    for (var i = 0; i < contacts.length; i ++) {
    }
};

list();


Inside of the loop, add code to call printPerson, passing in the element of the array that the loop is currently at.
At the very bottom of the file, call the list function. The list function should then loop through every member of the contacts array and print its information.
