wrong detect array length

(javascript)
if create array by:
~~~~~~~~~~~
var arr = [1, 2, 3,];
~~~~~~~~~~~
it will containt 3 elements, but "length"-property will contain number 4,
because the last comma. This is bug. Other browsers ignore it.

Can you fix it?

What, you want Microsoft to remove your comma for you? How many more of
your bugs do you want Microsoft to fix?

That's stupid - having a comma on the end shouldn't create a new array
element

It doesn't do it in other languages (PHP, Python, etc. etc.) and other
browsers implementations of Javascript
