Build ID: 20161123182536

Steps to reproduce:

typeof(Array())
typeof(document.getElementById('tableid').getElementsByTagName("tr").childNodes)


Actual results:

'object'
'object'


Expected results:

Array should really return a typeof() of 'array', not 'object', just like HTMLCollection should return 'htmlcollection' not 'object'. 'object is being used as a catch-all type when clearly-defined types exist.
htmlcollection should be tossed in favor of the array methods anyway (how do you delete a row or column? certainly not with slice)
