constructors in JS

Hi,

if I Have

var f = function Foo(){}

new f().constructor.prototype.constructor === Foo is true???

here the prototype object should have Object not Foo as constructor.

and

why new f().constructor.prototype.constructor.prototype.constructor is
always the same
while

new f().__proto__.__proto__.__proto__ end correctly with null?
