Javascript object to function namespacing

Question

I have an object like this

var a={
    b:{
        sayHi:function(){
            alert("hi");
        }
    }
}

I want to convert it into function name spacing using prototypes. How can I convert ? I tried following. but not working

var a=function(){};

a.prototype.b=function(){};

b.prototype.sayHi=function(){
        alert("hi");
}

var obj=new a();
obj.b.sayHi();

Any Help ?

Use this:

var A = function(){},
    B = function(){};
A.prototype.b = new B();
B.prototype.sayHi = function(){
        alert("hi");
}

var obj=new A();
obj.b.sayHi();
