What is the difference between “new Number(…)” and “Number(…)” in JavaScript?

Question

In Javascript, one of the reliable ways to convert a string to a number is the Number constructor:

var x = Number(\'09\'); // 9, because it defa         


        

Answer 1

Number (without new) doesn't seem to result exactly in a primitive. In the following example the anyMethod() is called (if in the Number prototype).

Number(3).anyMethod()

Whereas

3.anyMethod()

will not work.
