I see an incorrect algorithm in your solution but I don't really see what would be called an edge case (just to explain: anything divisible by 3 will enter the first conditional and omit the last, hence the algorithm you've used is incorrect). Or maybe we're talking about different things. Could you please explain to me in words what a fizzbuzz edge case would be ?
