In the previous blog post I explained that you should normally use an Immediately-Invoked Function Expression (IIFE) to give variables function scope. That works fine as log as we remember to declare our variables using the var keyword. However when we forget the var keyword we are back to the original problem as the variables are added to the global scope.
