Object-Oriented JavaScript

Number

Creates number objects:

>>> var n = new Number(101);
>>> typeof n

"object"

>>> n.valueOf();

101

Number objects are not primitive objects, but if you use a number method on a primitive number, the primitive will be converted to a Number object behind the scenes and the code will work.

>>> var n = 123;
>>> typeof n;

"number"

>>> n.toString()

"123"
