/*
 * Programming Quiz: Facebook Friends (7-5)
 */

/*
 * QUIZ REQUIREMENTS
 * - Your code should have an object `facebookProfile`
 * - The `facebookProfile` object should have the `name` (string), `friends` (number), and `messages` (array of strings) property
 * - Your `facebookProfile` object should have the `postMessage()`, `deleteMessage()`, `addFriend()` and `removeFriend()` method
 * - Carefully implement the desired functionality of each method, as decribed above
 */


// TIP - 
// In an array, 
// - addition at the end is done using push() method
// - addition at a specific index is done using splice() method
// - deletion from the beginning is done using pop() method
// - deletion from a specific index is done using splice() method

```python
var facebookProfile = {
    name: "Moonman",
    friends: 6,
    messages: ["wowowowo", "wha", "yeeee", "heee"],
    postMessage: function(message) {
        return facebookProfile.messages.push(message);
    },
    deleteMessage: function(index) {
        return facebookProfile.messages.splice(index,1);
    },
    addFriend: function(num) {
       return  facebookProfile.friends+= num;
    },
    removeFriend: function(num) {
        return facebookProfile.friends-= num;
    }
};```

facebookProfile.postMessage("beep");//add beep into message
facebookProfile.deleteMessage(1,1);//delete 'wha'
facebookProfile.addFriend(6);//any num of friend you'd like to add
facebookProfile.removeFriend(2);//any num of friend you'd like to remove
console.log(facebookProfile.messages);
console.log(facebookProfile.friends);
