class Person {
  constructor(name){ this.name = name; }
  greet(){ console.log(`Hi, I’m ${this.name}`); }
  get upperName(){ return this.name.toUpperCase(); }
  set rename(val){ this.name = val; }
  static species(){ return 'Homo sapiens'; }
}

  constructor(name, role){ super(name); this.role = role; }
  greet(){ super.greet(); console.log(`My role is ${this.role}`); }
}
