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
}

我会这样做:

function renameKeys(dict, keyMap) {
  return _.reduce(dict, function(newDict, val, oldKey) {
    var newKey = keyMap[oldKey] || oldKey
    newDict[newKey] = val 
    return newDict
  }, {})
}

如果你不想改变你的数据，考虑这个函数…

renameProp = (oldProp, newProp, { [oldProp]: old, ...others }) => ({
  [newProp]: old,
  ...others
})

下面是一个typescript友好的版本:

// These generics are inferred, do not pass them in.
export const renameKey = <
  OldKey extends keyof T,
  NewKey extends string,
  T extends Record<string, unknown>
>(
  oldKey: OldKey,
  newKey: NewKey extends keyof T ? never : NewKey,
  userObject: T
): Record<NewKey, T[OldKey]> & Omit<T, OldKey> => {
  const { [oldKey]: value, ...common } = userObject

  return {
    ...common,
    ...({ [newKey]: value } as Record<NewKey, T[OldKey]>)
  }
}

它将防止您破坏现有的键或将其重命名为相同的东西

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);

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' };

您可以尝试lodash _mapkeys。

Var用户= { 名称:“安德鲁”, id: 25日 报道:假 }; Var重命名= _。mapKeys(用户，函数(值，键){ 返回键+ "_" + user.id; })； console.log(重命名); < script src = " https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.js " > < /脚本>
