Hi, I just tried some example for javascript's for in statement.
I tried in in where the mootool has been preselected.
I don't know anything about mootools, but if you take a look at the example and run it, you will see, that all items in the array are shown perfectly, but after all items in the array, some other stuff is shown. It looks like that are some mysterious items in that array. If I select another framework in fiddle (jQuery) the array is traversed correctly.

Use ["Chris", "Kate", "Steve"].each(function(item, key){ ... }) or for (var i = 0; i < array.length; i++){ ... } loops. Not for-in loops for arrays.
