Get JavaScript array element object and its type

I'm creating an object using a Web Audio API library:

var player = new Pizzicato.Sound({
                source: 'file',
                options: {
                    path: 'file.mp3',
                    volume: 0.5
                }
            });

if I log the object in the console I get this image:

What I'm trying to do is to get the type name highlighted in the image, o.Effects.StereoPanner and store it in a variable but I can't get it. I can reach the effects array with player.effects[0] but that gives me the whole object and not its name. I can't even reach the elements of the array as player.effects[0] givesundefined`. Àny clue about how can I get that element and its type?

What do you mean by getting it *highlighted*? – Chris Jan 16 '17 at 18:06
I mean in the image – Diego Vega Jan 16 '17 at 18:07
Is that your entire attempt to access the image in code? – zer00ne Jan 16 '17 at 18:09

So, you're trying to get the name of the type of object located in `player.effects[0]`? You mention the property name, but that's just `"0"`. – Heretic Monkey Jan 16 '17 at 18:10
I'm trying to get the `o.Effects.StereoPanner` string – Diego Vega Jan 16 '17 at 18:11
Right, which is the name of the type, not the name of the property. See http://stackoverflow.com/q/332422/215552 – Heretic Monkey Jan 16 '17 at 18:11

You'd probably want to do something like "typeof o.Sound.effects [ 0 ]" – Tim Consolazio Jan 16 '17 at 18:14
Sound.effects [0], or player.effects[0] in this case, gives undefined – Diego Vega Jan 16 '17 at 18:38
