Class variable using Class syntax in Javascript

Question

I'd like to know if Javascript's class syntax support static, or class variables in the following way

class MyClass {
  var myVar = 0;

  //I have also tried these combinations of keywords
  static var myVar = 0;
  static myVar = 0;
  this.myVar = 0;
  this.var myVar = 0;
}

MyClass.myVar //0

I see that this is possible using the this keyword when defining a class with the function keyword, but I don't see if it's possible using class. I would hope it is, considering the class syntax supports static functions. I have tried the following.

I do not wish to use the constructor method, because then the variable would be an instance variable, and that's not what I'm asking for.
