Array(3) doesn't create [undefined, undefined, undefined, ]; it creates [/* hole */, /* hole */, /* hole */, ]. The holes don't set any property on the array whatsoever, so they are skipped when iterating. How this makes sense, I can't tell you.

Yet the array contains exactly three nothings.

It's like a zen koan.
