It seems to me that FunctionTemplate::Inherit does not allow multiple

Is that right?
Thanks!
That's correct, it's standard JS prototypal
In terms of hidden classes, there shouldn't be a difference.
However, since you're setting valueA and valueB in the constructor, setting
them on the prototype too seems entirely pointless to me. The prototype's
values are never visible from instance objects, right? Unless you want to
delete them
Hello everyone,
I'm trying to implement RequireJS on my JS Engine based on v8 (v8 3.21). I
have a problem with asynchronous loading and evaluation of scripts.
The main thread initialize v8 : create its isolate, context, script etc ..
When the main script is ready, the current isolate is

Hi,
When I create many objects new Machine like this
```
function Machine(power) {
var enabled = false;
this.enable = function() {
enabled = true;
};
this.disable = function() {
enabled = false;
};
Hi Ben,
Is that somehow related with Hidden classes for objects or that's a
completely another optimization technique?

The following drops the need for the closure, and lets v8 optimize nicely.
Unfortunately you lose the hidden aspect of the internal state.
function Machine(power) {
this.enabled = true;
}
Machine.prototype.enable = function() {
this.enabled = true;
};
Machine.prototype.disable() {
Hi Stefan,
I'm asking to deeper understand V8.
What's going on in the original code (see first message) which leads to
single-function-per-many objects?

Understood.
This message just caught my attention, as I am often sad that state hidden
by closure comes with a relatively high price compared to the state
existing on this.
Anyways, my tests also indicate the function bodies are correctly shared,
leaving only the captured context duplicated.

Hidden classes and closures are somewhat orthogonal, they don't
overlap much. See [1] and [2] for good
Thanks, Ben!
I was following the example in test-api.cc and it seemed to have worked for
me. I just wanted to make sure that I understand the difference between
FunctionTemplate.InstanceTemplate() and
FunctionTemplate.PrototypeTemplate():

Correction: I meant to say that Internal field count needs to be set on
_instance_ template for it to take effect on the instances created on
instance template. Is that right?
