递归地更改对象的所有键

function recursiveChangeKeys(obj, newKey) {
  if (typeof obj !== 'object' || obj === null) {
    return obj;
  }

  if (Array.isArray(obj)) {
    return obj.map(item => recursiveChangeKeys(item, newKey));
  }

  const newObj = {};
  for (const key in obj) {
    if (obj.hasOwnProperty(key)) {
      const value = obj[key];
      const newObjectKey = key === 'oldKey' ? newKey : key;
      newObj[newObjectKey] = recursiveChangeKeys(value, newKey);
    }
  }

  return newObj;
}

// 示例用法
const data = {
  oldKey: 'value',
  nestedObject: {
    oldKey: 'nestedValue',
    nestedArray: [
      { oldKey: 'arrayValue1' },
      { oldKey: 'arrayValue2' }
    ]
  }
};

const newData = recursiveChangeKeys(data, 'newKey');
console.log(newData);
