Problem with Multi-Level inheritance

This does work, but I really would like to use class notation.

var A = function() {};

var B = function() {
  A.call(this);
};
B.prototype = Object.create(A.prototype);
B.prototype.constructor = B;

var C = function() {
  B.call(this);
};

C.prototype = Object.create(B.prototype);
C.prototype.constructor = C;

function onInit() {
  const c = new C();
}
