I'm trying to understand the scope of variables in javascript when it comes to web-pages. For example, if I have let's say an index.html and I define two scripts

script One

var x = 2

script Two

var y = x

Would this work? Do both scripts work from a global pool of variables or are they each given their own space to work in?

Yes, both scripts are executed in the same, global scope. – Bergi Mar 03 '14 at 19:04
