'a' and 'b' could contain anything, so we can't just assign a = 2, b = 1. Also in your answer, you have declared the variable name 'myNumber' twice. I don't think that is permitted in that context.

Here's the solution:

var a = 1;
var b = 2;

// swap 'a' and 'b'

var temp = a;  // contains 1
a = b;  // contains 2
b = temp;  // contains 1

Does that make sense?

I see... It's above my pay-grade, haha! Tomorrow I will pick up a book JavaScript for Kids I ordered from Amazon. Do you prefer to study from books or from online sources?
