// turning live collection into static array fixes this
Array.slice(document.getElementsByTagName('div')).forEach(function(el) {
el.parentNode.removeChild(el);
});
Where supported, though top level generics such as Array.slice are not
standard, so:
var divList = document.getElementsByTagName('div');
Array.prototype.slice.call( divList );

Ok. I understand the "Array.slice" now. Sorry.
"Array.prototype.slice.call( divList );" is not standard either. In
ECMAScript 5, it is stated that :
"The slice function is intentionally generic; it does not require that
its this value be an Array object. Therefore it can be transferred to
other kinds of objects for use as a method. Whether the slice function
can be applied successfully to a host object is implementation-dependent."
Somehow, the reason why I am proposing that HTMLCollections inherit from
Array.prototype is to get rid of the "implementation-dependant" for
HTMLCollections which are clearly very good candidates for methods such
as forEach, filter (returns a new array (which would be a convinient way
to create static copies in one call)) or some/every.
