Reference count of a javascript object

[nearest-river]

Summary

I need to obtain the reference count of an object..
I'm trying to make a callback function invoke on ref-count change..

Additional Details

I just need to know where the javascript objects are stored and the memory layout of them..

JsValues don't use reference counting. Each JsValue contains the index of its value in a global JS array called heap: when they're cloned, the JS value gets copied to another spot in the array and the new JsValue contains the index of that new spot.

That means that it's left to the JavaScript garbage collector to figure out when there are no more references to a JS value.
