Why is arguments.callee.caller.name undefined?

Question

How come this doesn\'t alert \"http://127.0.0.1/sendRequest\"? (Available at http://jsfiddle.net/Gq8Wd/52/)

var foo = {
    sendRequest: function() {
        ale

If you do this:

var foo = {
    sendRequest: function() {
        alert(bar.getUrl());
    }
};                    

var bar = {
    getUrl: function() {
        return  arguments.callee;
    }
};

foo.sendRequest();

You will notice that the function doesn't have name which is true:

function() {

This is anonymous function.

You can name you method : sendRequest: function myMethodName() {
