What is the bug that can result from the "for(var i=0)" pattern? None, beause browsers ignore the second var for the same variable and do te ituitively right thing. What's the bug that results from the "var i; for(i=0)" pattern? Someone refactors the "var i" away and you end up with a global var. So, really, while the pedantic answer is to forbid the pattern, the pragmatic answer is to recommend it.
