OO [removed] Definitive explanation of variable scope

Question

Can someone provide an explanation of variable scope in JS as it applies to objects, functions and closures?

Answer 1

Variables not declared with var are global in scope. Functions introduce a scope, but note that if blocks and other blocks do not introduce a scope.

I could also see much information about this by Googling Javascript scope. That's really what I would recommend. http://www.digital-web.com/articles/scope_in_javascript/
