在寻找了很多答案后，这是我最好的解决方案:

const renameKey = (oldKey, newKey) => {
  _.reduce(obj, (newObj, value, key) => {
    newObj[oldKey === key ? newKey : key] = value
    return newObj
  }, {})
}

很明显，它没有替换原来的键，而是构造了一个新对象。 问题中的方法有效，但会改变对象的顺序，因为它将新的键-值添加到最后一个对象上。

使用对象解构和展开运算符的变体:

const old_obj = {
    k1: `111`,
    k2: `222`,
    k3: `333`
};    

// destructuring, with renaming. The variable 'rest' will hold those values not assigned to kA, kB, or kC.
const {
    k1: kA, 
    k2: kB, 
    k3: kC,
    ...rest
} = old_obj;
    

// now create a new object, with the renamed properties kA, kB, kC; 
// spread the remaining original properties in the 'rest' variable
const newObj = {kA, kB, kC, ...rest};

对于一个键，这可以很简单:

const { k1: kA, ...rest } = old_obj;
const new_obj = { kA, ...rest }

你也可能喜欢更“传统”的风格:

const { k1, ...rest } = old_obj
const new_obj = { kA: k1, ...rest}

const clone = (obj) => Object.assign({}, obj);

const renameKey = (object, key, newKey) => {

    const clonedObj = clone(object);
  
    const targetKey = clonedObj[key];
  
  
  
    delete clonedObj[key];
  
    clonedObj[newKey] = targetKey;
  
    return clonedObj;
     };

  let contact = {radiant: 11, dire: 22};





contact = renameKey(contact, 'radiant', 'aplha');

contact = renameKey(contact, 'dire', 'omega');



console.log(contact); // { aplha: 11, omega: 22 };

重命名键，但避免改变原始对象参数

oldJson=[{firstName:'s1',lastName:'v1'},
         {firstName:'s2',lastName:'v2'},
         {firstName:'s3',lastName:'v3'}]

newJson = oldJson.map(rec => {
  return {
    'Last Name': rec.lastName,
    'First Name': rec.firstName,  
     }
  })
output: [{Last Name:"v1",First Name:"s1"},
         {Last Name:"v2",First Name:"s2"},
         {Last Name:"v3",First Name:"s3"}]

最好有一个新的数组

我的方法，改编好的@Mulhoon typescript帖子，用于更改多个键:

const renameKeys = <
    TOldKey extends keyof T,
    TNewkey extends string,
    T extends Record<string, unknown>
>(
  keys:  {[ key: string]: TNewkey extends TOldKey ? never : TNewkey },
  obj: T
) => Object
    .keys(obj)
    .reduce((acc, key) => ({
        ...acc,
        ...{ [keys[key] || key]: obj[key] }
    }), {});

renameKeys({id: 'value', name: 'label'}, {id: 'toto_id', name: 'toto', age: 35});

尝试使用lodash transform。

var _ = require('lodash');

obj = {
  "name": "abc",
  "add": "xyz"
};

var newObject = _.transform(obj, function(result, val, key) {

  if (key === "add") {
    result["address"] = val
  } else {
    result[key] = val
  }
});
console.log(obj);
console.log(newObject);
