How can I get the name of function inside a JavaScript function?

Question

How is it possible to learn the name of function I am in?

The below code alerts 'Object'. But I need to know how to alert "Outer."

function Outer(){

    alert(typeof this);

}

I think that you can do that :

var name = arguments.callee.toString();

For more information on this, take a look at this article.

function callTaker(a,b,c,d,e){
  // arguments properties
  console.log(arguments);
  console.log(arguments.length);
  console.log(arguments.callee);
  console.log(arguments[1]);
  // Function properties
 console.log(callTaker.length);
  console.log(callTaker.caller);
  console.log(arguments.callee.caller);
  console.log(arguments.callee.caller.caller);
  console.log(callTaker.name);
  console.log(callTaker.constructor);
}

function callMaker(){
  callTaker("foo","bar",this,document);
}

function init(){
  callMaker();
}
