重命名对象数组JS中的嵌套键

const data = [
  { user: { name: 'Alice', age: 25 } },
  { user: { name: 'Bob', age: 30 } }
];

function renameNestedKeys(obj, keyMap) {
  if (Array.isArray(obj)) {
    return obj.map(item => renameNestedKeys(item, keyMap));
  } else if (typeof obj === 'object' && obj !== null) {
    return Object.keys(obj).reduce((acc, key) => {
      const newKey = keyMap[key] || key;
      acc[newKey] = renameNestedKeys(obj[key], keyMap);
      return acc;
    }, {});
  }
  return obj;
}

const data = [
  { user: { name: 'Alice', age: 25 } },
  { user: { name: 'Bob', age: 30 } }
];

const keyMap = {
  user: 'userInfo',
  name: 'fullName',
  age: 'userAge'
};

const transformedData = renameNestedKeys(data, keyMap);
console.log(transformedData);

[
  { userInfo: { fullName: 'Alice', userAge: 25 } },
  { userInfo: { fullName: 'Bob', userAge: 30 } }
]
