javascript - 访问对象 key :Value Pair in Function

Question

当我运行此代码时，我无法将其发送到 console.log 我正在寻找的答案。当我运行代码时，我得到 NaN 。如何让这个函数将对象 MysteryNumber 值相乘并返回结果？

const mysteryNumberObject = {
  mysteryNumber: 5,
};

function multiplyMysteryNumberByFive(mysteryNumberObject) {
  for(let key in mysteryNumberObject) {
    console.log(key * 5);
  }
};

multiplyMysteryNumberByFive(mysteryNumberObject);

Answer 1

对象中唯一的键是“magicNumber”，将其乘以 5 没有任何意义。我认为您想获取对象的值:

function multiplyMysteryNumberByFive(mysteryNumberObject) {
  for(let value of Object.values(mysteryNumberObject)) {
    console.log(value * 5);
   }
}
