Answer 1

Add a semicolon or {} at the end of the for loop in your original code.

Answer 2

First and foremost, you were concatenating n with only one zero ie 0+n.
For the explanation, you are using prototypical inheritance. Every object in JS has a prototype object assigned to it. What
you are doing is assigning a pad() method to the Number Object, so any object of number type will have access to the pad() method.

I think the rest is the for loop and I think u know the syntax.
