Is it possible to call a super setter in ES6 inherited classes?

Question

I\'m wondering if the following is in compliance with the ES6 spec:

class X {
  constructor(name) {
    this._name = n         


        

Answer 1

class Y extends X {
  constructor(name) {
    super(name);
  }

  set name(name) {
    super.name = name;
    this._name += "Y";
  }
}

will override the name properly with an accessor for just the setter, with no getter. That means your y.name === "hiXY" will fail because y.name will return undefined because there is no getter for name. You need:

class Y extends X {
  constructor(name) {
    super(name);
  }

  get name(){
    return super.name;
  }

  set name(name) {
    super.name = name;
    this._name += "Y";
  }
}
