Question

This is a follow-up question to this one.

Take a look at these two examples:

var number1 = new Number(3.123); number1 = number1.toFixed(2);  alert(number1);  var number2 = 3.123; number2 = number2.toFixed(2); alert(number2); 

I realize they both end up with the same value, but is it correct thinking to refer to a method of a primitive value? (In other words, 3.123.method as opposed to object.method?)

Answer 1

In JavaScript, everything is an object, even functions and integers. It is perfectly OK to think of methods on numbers and strings. For example:

>>> (3.123).toString() '3.123'
