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。

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

下面是创建具有重命名键的新对象的示例。

let x = { id: "checkout", name: "git checkout", description: "checkout repository" };

let renamed = Object.entries(x).reduce((u, [n, v]) => {
  u[`__${n}`] = v;
  return u;
}, {});

为每个键添加前缀:

const obj = {foo: 'bar'}

const altObj = Object.fromEntries(
  Object.entries(obj).map(([key, value]) => 
    // Modify key here
    [`x-${key}`, value]
  )
)

// altObj = {'x-foo': 'bar'}

简单地这么做会有什么问题吗?

someObject = {...someObject, [newKey]: someObject.oldKey}
delete someObject.oldKey

如果愿意，可以将其包装在函数中:

const renameObjectKey = (object, oldKey, newKey) => {
    // if keys are the same, do nothing
    if (oldKey === newKey) return;
    // if old key doesn't exist, do nothing (alternatively, throw an error)
    if (!object.oldKey) return;
    // if new key already exists on object, do nothing (again - alternatively, throw an error)
    if (object.newKey !== undefined) return;

    object = { ...object, [newKey]: object[oldKey] };
    delete object[oldKey];

    return { ...object };
};

// in use
let myObject = {
    keyOne: 'abc',
    keyTwo: 123
};

// avoids mutating original
let renamed = renameObjectKey(myObject, 'keyTwo', 'renamedKey');

console.log(myObject, renamed);
// myObject
/* {
    "keyOne": "abc",
    "keyTwo": 123,
} */

// renamed
/* {
    "keyOne": "abc",
    "renamedKey": 123,
} */

我想这么做

const originalObj = {
  a: 1,
  b: 2,
  c: 3, // need replace this 'c' key into 'd'
};

const { c, ...rest } = originalObj;

const newObj = { ...rest, d: c };

console.log({ originalObj, newObj });
