function object and prototype.

function aa() {};
var bb = new aa();

var dd = new function cc() {};

aa.prototype.rr = 100;
cc.prototype.rr = 100;

---------------------------------------------------------------

i wrote the code above that makes two functions and two object for
those.

bb(object)->aa(function),
dd(object)->cc(function).

i think it's all the same way to make an object for a function.

but if u try to debug,

bb object has rr right after "aa.prototype.rr = 100" statement
but dd deosn't have rr variable.

isn't dd obj refer to cc?

can anyone explain it why?

thanks in advance.

funny singletons maybe) - for the time being just pretend it doesn't
exist and use the conventional JavaScript object model.

If browsers get past where Safari errors, they will throw one at this
point: window.cc is not defined, attempting to access its prototype
property is doomed to failure.

The reference provided by VK is a good one.

It isn't.

Because an rr property was never added to dd or any object in its scope
chain.
dd refers to a function object constructed using the anonymous object
passed to the new operator (except in Safari :-) ). The anonymous
function named cc has probably already ceased to exist.
