Reference in my book, in Javascript or any other language,
is transferring the variable-pointer or object-pointer and not the value.

The fact is, 
that in Javascript objects are passed by their pointer. 

In other words, their pointer IS their value.

So this clearly is passing by reference.

That in othr languages you can choose 
does not mean that in Javascript objects are not passed by reference.
