is it possible in Javascript to tell an object to stop having reference behavior with another object
<p>Just getting back into doing a lot of Javascript and trying to understand Javascript objects better. I asked previous question earlier but this one is different. Can I disconnect a reference relationship that exists between objects?</p>

<p>For example:</p>

<pre><code>var objA={};
objA.my_name='Joe';
var objB=objA;
objB.my_name="jake"; // objA.my_name="jake"
objB.something="this is something";
objA.last_name="Jackson";
console.log(objA.something);  // "this si something" can add to parent object at runtime
console.log(objB.last_name);  // "Jackson" can add to child object at runtime
// now I'd like to cut off objB from objA such that:
objB.cell_phone='323-213-2323';
console.log(objA.cell_phone); // '323-213-2323' but would like undefined; would like this behavior
</code></pre>

<p>thx in advance</p>
