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
