What is the purpose of the var keyword and when should I use it (or omit it)?
...
It's like shooting oneself with a railgun... Forget to put a 'var' before one's variable, and end up modifying a variable somewhere in the scope chain... Try convincing a Java/C/Python/etc. developer that JavaScript is worthwhile. Ha! C/C++ pit...
