Subj : Hook into Array

Is there a way to hook into predefined classes e.g. the Array class to get
notifications when individual objects are inserted/reassigned/deleted, or
when the entire Array is sorted or reversed?

Also, is there a way to not initialize array elements until its values are
requested? Currently I'm initializing all elements right after the
JS_NewArray call, which is rather time consuming when only a few elements
actually are needed in the script. My arrays could contain 100,000+
elements. The only idea I've came up with so far is to skip the Array
alltogther, and expose a function returning objects by index.

By the way, are there any constraints regarding the number of elements to
the Array class, except runtime memory?

Oops, ended up with three questions in one...
Thanks in advance.
