Object Reference Mechanism in JavaScript

Object Reference Mechanism: objects are not copied and can only be passed through references.
Simple Example:

Var I = mangguo ={}; // whether empty or not
Mangguo. address = 'hangzhou'; the value of mangguo. address is the same as that of I. address because I and mangguo reference the same object.
However, if two empty objects, I and mangguo, are declared respectively:

Var I = {},
Mangguo ={}; at this time, I and mangguo are two different Null Object references.
