Javascript arguments.callee what is it for

Question

I haven\'t found any complete cross-browser doc of this variable.

What is arguments.callee for? how does it work?

Which arguments does it have?

Answer 1

It specifies the currently executing function, so arguments.callee is the current function. It may be helpfull if you need to go recursive in anonimous function. Here example from mozilla:

function create() {
   return function(n) {
      if (n <= 1)
         return 1;
      return n * arguments.callee(n - 1);
   };
}

var result = create()(5); // returns 120 (5 * 4 * 3 * 2 * 1)
