Looping over object values works as intended, but first value is undefined?

Question

Hi there!

Could someone explain to me why objectInfo method on the third button returns undefined for the first value? http://jsfiddle.net/PnSSX/11/

I can't figure out where this comes from, because there is no property before name...

Can you help? Am I missing something?

Best regards, shapeshifta

It's because loop is initially undefined and you're calling += so it gets a converted to a string, to fix it, change this:

var loop;

To this:

var loop = "";
