Number #length
Specifies the number of arguments expected by the function.

Method Summary
void #apply()
Applies the method of another object in the context of a different object (the calling object); arguments can be passed as an Array object.
void #bind()
Creates a new function which, when called, itself calls this function in the context of the provided value, with a given sequence of arguments preceding any provided when the new function was called.
void #call()
Calls (executes) a method of another object in the context of a different object (the calling object); arguments can be passed as they are.
String #toString()
Returns a string representing the source code of the function.

Property Details
constructor
Specifies the function that creates an object's prototype.
Returns
Function
Sample 
function Tree(name) {
	this.name = name;
}
theTree = new Tree("Redwood");
application.output("theTree.constructor is " + theTree.constructor);
length
Specifies the number of arguments expected by the function.
Returns
Number
Sample 
function addNumbers(x, y){
	if (addNumbers.length == 2) {
		return (x + y);
	} else
		return 0;
}

Method Details
apply

void apply ()

Applies the method of another object in the context of a different object (the calling object); arguments can be passed as an Array object.
Returns
void
Sample 
function book(name, author) {
	this.name = name;
	this.author = author;
}

function book_with_topic(name, author, topic) {
	this.topic = topic;
	book.apply(this, arguments);
}
book_with_topic.prototype = new book();

var aBook = new book_with_topic("name","author","topic");
bind

void bind ()

Creates a new function which, when called, itself calls this function in the context of the provided value, with a given sequence of arguments preceding any provided when the new function was called.
Returns
void
Sample 
var x = 9,
	module = {
		getX: function() {
		     return this.x;
		},
		x: 81
	};
//  "module.getX()" called, "module" is "this", "module.x" is returned
module.getX(); // > 81
//  "getX()" called, "this" is global, "x" is returned
getX(); // > 9
//  store a reference with "module" bound as "this"
var boundGetX = getX.bind(module);
//  "boundGetX()" called, "module" is "this" again, "module.x" is returned
boundGetX(); // > 81
call

void call ()

Calls (executes) a method of another object in the context of a different object (the calling object); arguments can be passed as they are.
Returns
void
Sample 
function book(name) {
	this.name = name;
}

function book_with_author(name, author) {
	this.author = author;
	book.call(this, name);
}
book_with_author.prototype = new book();

var aBook = new book_with_author("name","author");
toString

String toString ()

Returns a string representing the source code of the function. Overrides the Object.toString method.
Returns
String
Sample 
function printHello() {
		return "Hello";
}
