It's not even an issue in languages (C) that don't strongly type for performance reasons, or because you get closer hardware access as a result (though these count as features themselves). The problem is that in Javascript, you don't get either of these -- there's no benefits, there are only new bug vectors. This wouldn't be as big of an issue if the default coercion behaviour was generally helpful, but it's not. It's just a pain.
