11,033 Pointsplaylist instead of Playlist constructor? but why..
around the 7:10 to 7: 30 duration in the video
we can see the code uses
playlist.play
playlist.next
playlist.stop
yet in the playlist.js file it is clear to see that the constructor is Playlist with a capital P as seen below. is this referenceing the playlist.js file is that why it is lower case?
Playlist.prototype.play = function() {
var currentSong = this.songs[this.nowPlayingIndex];
currentSong.play();
};
Playlist.prototype.stop = function(){
this.stop();
this.nowPlayingIndex++;
if(this.nowPlayingIndex == this.songs.length){
this.nowPlayingIndex = 0;
};
this.play();
};

Treehouse TeacherNo. In app.js on the first line at the start of the video you have this line:
var playlist = new Playlist();
This creates a new instance of a Playlist object which will now be referenced to simply as playlist. In reality, you could have named this any valid JavaScript variable name. For example, myPlaylist or yourPlaylist. Those would then be referenced by those names.
Hope this helps!
