Nonsense.  It is perfectly OK for a function/method to return a reference to 
a native object, and no names/identifiers are necessary to refer to it.

  (function () {
    "use strict";

    var _foo = "baz";

    return {
      bar: function () { console.log(_foo); }
    };
  }()).bar();

References are _not_ "values that can be assigned to".

_“getElementById”_ (case matters) and “innerHTML” are not "entries from a 
DOM"; *the* DOM is a concept and an API.  But they are properties of DOM 
element objects, that which implement the (HTML)Element interface of the W3C 
and WHATWG DOMs.  Of those properties the “innerHTML” property is 
proprietary, i.e. there is no public standard that specifies it or an 
interface with an attribute of the same name.

Not even wrong.

You have yet to learn that “JavaScript” reasonably can only refer to a 
subset of ECMAScript implementations, namely those that carry the name.
IOW, it is not just one programming language that you are dealing with here, 
not even if you limit yourself to Web browsers.  (You have been told this 
/ad nauseam/ already, but your record strongly indicates that you are too 
full of yourself to reconsider any of your preconceptions when the flaws in 
them are pointed out to you.)

Given your many misconceptions that you so readily display here, I still 
seriously doubt that it is of advantage to take any of your courses (which, 
JFTR, take place either online for free or in a *Volkshochschule* [German 
adult education center], not in any institution of higher education) in the 
first place.  In fact, at this point I must recommend against taking them, 
at least with regard to “JavaScript”.  Students will be much better off 
reading MDN articles, de.comp.lang.javascript, and this newsgroup instead.
