That *your* code, that *you* *think* is implementing my approach, which you 
do not show, is not working as you expect, does not invalidate *my* approach 
and *my* code that I wrote to implement it.

Even though my originally posted code has that bug that *I* have found as 
you forced me to look at it again: When *actually* called with deepCopy === 
true, it only copies *one* level deep.

Look more carefully at the code again, read my follow-up again, and do read 
my other follow-up; you appear to have the common misconception of "nested 
objects" in ES.
