Closure object (Object/internal)

A special kind of function object that preserves prototype inheritance and scope.


JavaScript - 1.2
Netscape - 4.0
JavaScript syntax:NmyClosure = new Closure()
Object properties:__parent__, __proto__

This is a special kind of object, which maintains some contextual state information when it is created.

It can behave like a function, but is a kind of function wrapper that references a function and a scope. Since it inherits everything from the Function object, it can behave like a function and can be called as such.

Because it also stores the scope chain at the time it is manufactured, it can restore that scope chain when it is executed.
