Object Summary

Provides functionality common to all JavaScript objects.

Syntax 
obj  = new Object( [ value ] )
obj
Required. The variable name to which the Object object is assigned.
value
Optional. Any one of the JavaScript primitive data types (Number, Boolean, or String). If value is an object, the object is returned unmodified. If value is null , undefined , or not supplied, an object with no content is created.
Remarks

The Object object is contained in all other JavaScript objects; all of its methods and properties are available in all other objects. The methods can be redefined in user-defined objects, and are called by JavaScript at appropriate times. The toString method is an example of a frequently redefined Object method.

In this language reference, the description of each Object method includes both default and object-specific implementation information for the intrinsic JavaScript objects.
