Usage

arguments.callee:Function

Description

Property; refers to the function that is currently being called.

Example

You can use the arguments.callee property to make an anonymous function that is recursive, as shown in the following example:

factorial = function (x:Number) {
   if (x<=1) {
      return 1;
   } else {
      return x*arguments.callee(x-1);
   }
};
trace(factorial(3));  // output: 6

The following example is a named recursive function:

function factorial(x:Number):Number {
   if (x<=1) {
      return 1;
   } else {
      return x*factorial(x-1);
   }
}
trace(factorial(4));  // output: 24
