Where is function Empty() {}?

Question

In Chrome,

(function(){}).__proto__

is

function Empty() {}

so I would have expected

new Function();

to be function Empty() {}, but instead it is function anonymous() {}.

Where can I find function Empty() {}? Is it in Function or Object somewhere?

Those names don't mean you can access them with those identifiers.

As for the prototype of a function, the name is set at startup. That function has been set a name but it doesn't really serve any purpose other than .name and .toString() exposing it.

As for a new Function() instance, the name is merely printed for .toString(). So .name is still the empty string. Again, it doesn't serve much purpose.
