如何以可迭代方式重命名对象属性

const renameKeys = (obj, keysMap) => {
  return Object.keys(obj).reduce((acc, key) => {
    const newKey = keysMap[key] || key;
    acc[newKey] = obj[key];
    return acc;
  }, {});
};

// 示例
const originalObj = { a: 1, b: 2, c: 3 };
const keysMap = { a: 'alpha', b: 'beta' };

const newObj = renameKeys(originalObj, keysMap);
console.log(newObj); // 输出：{ alpha: 1, beta: 2, c: 3 }

const renameKeysInPlace = (obj, keysMap) => {
  for (const key in obj) {
    if (keysMap.hasOwnProperty(key)) {
      const newKey = keysMap[key];
      obj[newKey] = obj[key];
      delete obj[key];
    }
  }
};

// 示例
const originalObj = { a: 1, b: 2, c: 3 };
const keysMap = { a: 'alpha', b: 'beta' };

renameKeysInPlace(originalObj, keysMap);
console.log(originalObj); // 输出：{ alpha: 1, beta: 2, c: 3 }

const renameKeysUsingEntries = (obj, keysMap) => {
  return Object.entries(obj).reduce((acc, [key, value]) => {
    const newKey = keysMap[key] || key;
    acc[newKey] = value;
    return acc;
  }, {});
};

// 示例
const originalObj = { a: 1, b: 2, c: 3 };
const keysMap = { a: 'alpha', b: 'beta' };

const newObj = renameKeysUsingEntries(originalObj, keysMap);
console.log(newObj); // 输出：{ alpha: 1, beta: 2, c: 3 }
