1) Look at your specs and/or user stories

2) Highlight nouns in specs--those are likely candidates for objects

3) Highlight verbs in specs--those are likely candidates for methods

Note: Figuring out what objects should hold those methods can be a challenge, but generally an object should track its own info/be responsible for itself.

Nouns = objects

• User
• Tweet
• Newsfeed

Verbs = methods that go along with an object

User

• Post
• Like
• Retweet
• Follow

Tweet

• increaseLikes

Newsfeed

• Show

4) Code!

function User(name) {
  this.userName = name;
  this.tweets = [];
  this.followers = []
  this.follows = [];
}
User.prototype.post = function (message) {
  var newTweet = new Tweet(message);
  this.tweets.push(newTweet);
}
User.prototype.like = function (tweet) {
  tweet.likes += 1;
}

function Tweet(text) {
  this.text = text;
  this.likes = 0;
  this.retweets = 0;
}

function Newsfeed() {
  this.posts = []
}

Newsfeed.prototype.show(userId) {
// will get list of posts by all that user is following
}

And so on and so forth! 😄
