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"
