List of names of models in a Backbone.js Collection

I'm trying to learn a little bit of backbone.js and I'm getting stuck on something I think should be fairly simple to figure out. How do I get a list of all model names in a collection?

I'm even copy+pasting from the backbone tutorial:

var Song = Backbone.Model.extend({
    defaults: {
        name: "Not specified",
        artist: "Not specified"
    },
    initialize: function(){
        console.log("Music is the answer");
    }
});

var Album = Backbone.Collection.extend({
    model: Song
});

var song1 = new Song({ name: "How Bizarre", artist: "OMC" });
var song2 = new Song({ name: "Sexual Healing", artist: "Marvin Gaye" });
var song3 = new Song({ name: "Talk It Over In Bed", artist: "OMC" });

var myAlbum = new Album([ song1, song2, song3]);
console.log( myAlbum.models ); // [song1, song2, song3]

The problem is - this doesn't give me model names in the console: console.log( myAlbum.models ); // [song1, song2, song3]
instead I get [child, child, child, child] - how do I get the actual names?

You need to pluck the name attribute.

myAlbum.pluck('name');

There is no way to get an array like this:

['song1', 'song2', 'song3']

because names of variables are not available in program logic.

Update

When the tutorial writes this:

console.log( myAlbum.models ); // [song1, song2, song3]

It means that the array models is the same as if you were to write [song1, song2, song3], not as if you were to write ['song1', 'song2', 'song3']. The quotes are the differentiating factor.
