  constructor(name, gender) {
    this.name = name;
    this.gender = gender;
  }
 
  static getGenderFemale() {
    return "female";
  }
 
  static getGenderMale() {
    return "male";
  }
}

class MaleHuman extends Human {
  constructor(name) {
    super(name, Human.getGenderMale());
  }
}

class FemaleHuman extends Human {
  constructor(name) {
    super(name, Human.getGenderFemale());
  }
}

var jack = new Human("Jack", Human.getGenderMale());
