Well, a lot of the little issues are being slowly fixed (see let and scoping in ES6). This goes back to the point of the person you are responding to. This is a thought more than a full-fledged argument, but perhaps little issues with the language actually can and do make people better developers when they are aware of them. My friend started driving a scooter. Dallas isn't particularly conducive to that. My friend says he has since become a better driver because he knows one little screw up by him or someone else can end his life. Similarly, you'd better be aware of weak typing and casting and code accordingly or you might get hurt. Of course, you shouldn't have to...but that doesn't make people worse developers. But the truth is, JS has a lot of features which make it great for becoming a good developer. It's less class-based than Ruby and has better lambdas than Python which I would argue make it better for functional programming than either.
