  }
}

Person = class AnotherPerson {
  constructor() {
    this.name = 'Sarah';
  }
};

console.log(member.name);

• A: "Lydia"
• B: "Sarah"
• C: Error: cannot redeclare Person
• D: SyntaxError

Answer 1

Answer: B

We can set classes equal to other classes/function constructors. In this case, we set Person equal to AnotherPerson. The name on this constructor is Sarah, so the name property on the new Person instance member is "Sarah".
