如果你想保留迭代顺序(插入的顺序)，这里有一个建议:

const renameObjectKey = (object, oldName, newName) => {

  const updatedObject = {}

  for(let key in object) {
      if (key === oldName) {
          newObject[newName] = object[key]
      } else {
          newObject[key] = object[key]
      }
  }

  object = updatedObject
}

您可以使用实用程序来处理这个问题。

npm i paix

import { paix } from 'paix';

const source_object = { FirstName: "Jhon", LastName: "Doe", Ignored: true };
const replacement = { FirstName: 'first_name', LastName: 'last_name' };
const modified_object = paix(source_object, replacement);

console.log(modified_object);
// { Ignored: true, first_name: 'Jhon', last_name: 'Doe' };

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 };

在您最喜欢的编辑器中尝试一下

const obj = {1: 'a', 2: 'b', 3: 'c'}

const OLD_KEY = 1
const NEW_KEY = 10

const { [OLD_KEY]: replaceByKey, ...rest } = obj
const new_obj = {
  ...rest,
  [NEW_KEY]: replaceByKey
}

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});
