The short answer is no. JavaScript doesn't have a built in idea of
any sort of class hierachy.
The method you talked about (passing in a reference) is one of the
simplest (and probably easiest) ways to get hierachy/nesting into
JavaScript.
What marks is pointing too is a library that allows you to build
that heirachy in a consistant manner. I haven't needed to use it so I
can't vouch for it.

objects that are children of another object.

To do it in jquery I'II have to do some more reading
Hopes this helps

there a standard way to refer back to properties/methods in the parent

passing a reference to the new object (new engine(this) -- engine =
function(root){ this.root = root;} ) so I can get at methods easily,
but that seems messy. I don't like the thought of circular references
even if they are benign :)
