Math

Math is a different from the other built-in objects because it cannot be used as a constructor to create objects. It's just a collection of static functions and constants. Some examples to illustrate the difference are as follows:

    > typeof Date.prototype; 
    "object" 
    > typeof Math.prototype; 
    "undefined" 
    > typeof String; 
    "function" 
    > typeof Math; 
    "object"
