The Object object is the base object for all native and user-defined objects. All objects inherit from this superclass. You can create an Object object as well:

var myObject = new Object();
The Object object has a dozen of properties and methods. Examples are constructor, toString(), and valueOf(). The object myObject above sports these properties. Alert the object. You should get [object Object]. You can pass a string to the Object constructor:

var myObject = new Object("foo");
Alert the object. You should get the string you passed to the constructor, "foo". The native objects sports the same properties, because they inherit from the Object class. Probe the constructor property of the Math object, Math.constructor. The answer you should get is that the Object object is the constructor of the Math object.
