 * Create an object called facebookProfile. The object should have 3 properties:
 * your name
 * the number of friends you have, and
 * an array of messages you've posted (as strings)
 * The object should also have 4 methods:
 * postMessage(message) - adds a new message string to the array
 * deleteMessage(index) - removes the message corresponding to the index provided
 * addFriend() - increases the friend count by 1
 * removeFriend() - decreases the friend count by 1

    postMessage: function(message) {
        return facebookProfile.messages.push(message);
    },
    deleteMessage: function(index) {
        return facebookProfile.messages.splice(index,1);
    },
    addFriend: function() {
        return facebookProfile.friends+= 1;
    },
    removeFriend: function() {
        return facebookProfile.friends-= 1;
