That's strange, coming from Java.

That's a validation of some of the other discussion in the thread. JavaScript gets a 'class' keyword, but it's really just syntactic sugar over prototypical inheritance. So there is some misunderstanding about what it does and doesn't do.

That said, it could have also been written as:

  static set circlesMade(val) {
        Circle._count = val;
  };

which means the exact same thing, and would maybe help people to understand that "_count" is just like a static class property on the Circle "class"
