different between Object.create and new?

Hi there.

From what I understand, there really isn't any difference, as both will create a new Object. I found two MDN documentations that may help here.

MDN Object-Oriented Programming. For this one, scroll just under half way down the document to "Custom Objects.

MDN Object.create().

I hope this helps. Keep Coding! :)

• Object.create() passes/overwrites an object with another object (In this case Media.prototype onto Song.prototype).
• new generates an object from a function.

This app can be built without either of these.
By changing:

 Playlist.prototype.play = function () {
    var currentSong = this.playlist[this.nowPlayingIndex];
    currentSong.play();
};

to:

Playlist.prototype.play = function () {
    var currentSong = this.playlist[this.nowPlayingIndex];
    currentSong.isPlaying = true;
};

Same goes for stop and next. Now Media.prototype.play(), stop(), next() are redundant and you don't need to share them with Movie.prototype and Song.prototype.
