parameters when defining the function, we can rely on the arguments array passed to
the function to access parameters if they are sent upon invocation.
Sample: sample82.html
var add = function () {
return arguments[0] + arguments[1];
};
console.log(add(4, 4)); // Returns 8.
The this keyword, passed to all functions, is a reference to the object that contains the
function. As you might expect, functions contained within objects as properties (i.e.
methods) can use this to gain a reference to the parent object. When a function is
defined in the global scope, the value of this is the global object. Review the following
code and make sure you understand what this is returning.
Sample: sample83.html
var myObject1 = {
name: 'myObject1',
myMethod: function () { console.log(this); }
};
myObject1.myMethod(); // Logs 'myObject1'.
var myObject2 = function () { console.log(this); };
myObject2(); // Logs window.
The arguments.callee property
The arguments object has a property called callee, which is a reference to the
function currently executing. This property can be used to reference the function from
within the scope of the function (e.g., arguments.callee)—a self-reference. In the
following code, we use this property to gain a reference to the calling function.
