Hi,
I am curious on exactly how much memory an empty JS Object instance is
using in v8. How would I go about measuring this value? I am interested in
both 32bit and 64bit builds.
For example:
function Test() { }
var t = new Test; // The memory size of "t" instance internally?
>From the API I can see that each instance has an internal "hash value"
(ID). Also, it probably needs to store the [[Prototype]]. So that's two
numbers (the size of a pointer?).
And do I win any memory savings if I construct objects without the
prototype. As in:
... = Object.create(null);
And how are object references implemented? I assume they are essentially
pointers internally?
Thanks for any help in figuring this out,
Simas
