Javascript data types

Hi,

re: http://docs.webplatform.org/wiki/dom/Range/cloneRange

as Range and RangeError are not in the list at http://docs.webplatform.org/wiki/Property:Javascript_data_type

I end up with a nonsense Return Value description....

“Returns an object of type Object” 
[object Range]

I am pressed for time, so I have flagged the item as almost ready.... awaiting Range object to js data-types.

Comments/Advice?

...seems to me that the js object types should be open to editor discretion as ‘objects’ can be anything one wants....

var WPO={‘toString’:function(){return ‘[object WPO]’;}}

there are ‘core’ data-types... number, date, boolean, string, regex and Array, but what were once ‘object’ can now be [object Anything]

eg. var test=2; typeof test returns ‘number’

Regards.
