Synopsis
arguments.callee
Description
arguments.callee
refers to the function that is currently running. It provides a way
for an unnamed function to refer to itself. This property is defined
only within a function body.
Example
// An unnamed function literal uses the callee property to refer
// to itself so that it can be recursive
var factorial = function(x) {
if (x < 2) return 1;
else return x * arguments.callee(x-1);
}
var y = factorial(5); // Returns 120
