item() Method is a String Value - IE7

[dhtml]

In IE7, this:-

alert(document.body.childNodes.item === "[object]");

is true.

Why is childNodes.item returning "[object]" ?

Because it is a collection:

.item(0), .item(1), I think.

Item should be a Host object, not a string value. In fact, item() is
callable, so it could reasonably be considered a function
(implementation dependent). Method item() also seems to implement
[[call]] in IE:-
:-
javascript:alert(Function.prototype.call.call(document.body.childNodes,
document.body.childNodes.item, 0))

(But that's beside the point.)

My original example:-
alert(document.body.childNodes.item === "[object]");

Uses strict equality, ===

With strict equality, when comparing an object and a string value, the
result should be false (as is true with strict comparison of any two
obects of different types).

Is - item - an object or a string value?

It appears [[Get]] would find - item - on - childNodes - directly:-
javascript:alert(Object.prototype.hasOwnProperty.call(document.body.childNodes,
"item"))

I'm at a loss as to understand why [[Get]] returns "[object]" for the
- item - property.
