如果密钥名称未知，有没有办法访问json项？

const json = {
  key1: "value1",
  key2: "value2",
  key3: "value3"
};

const keys = Object.keys(json);
for (let i = 0; i < keys.length; i++) {
  const key = keys[i];
  const value = json[key];
  console.log(`Key: ${key}, Value: ${value}`);
}

const json = {
  key1: "value1",
  key2: "value2",
  key3: "value3"
};

for (let key in json) {
  const value = json[key];
  console.log(`Key: ${key}, Value: ${value}`);
}
