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>

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 });

如果你想保持对象的相同顺序

changeObjectKeyName(objectToChange, oldKeyName: string, newKeyName: string){
  const otherKeys = cloneDeep(objectToChange);
  delete otherKeys[oldKeyName];

  const changedKey = objectToChange[oldKeyName];
  return  {...{[newKeyName] : changedKey} , ...otherKeys};

}

使用方法:

changeObjectKeyName ( {'a' : 1}, 'a', 'A');

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 };

如果有人需要重命名object的键:

const renameKeyObject = （obj， oldKey， newKey） => { 如果 （旧键 === 新键） 返回 volj; Object.keys（obj）.forEach（（key） => { if （key === oldKey） { obj[newKey] = obj[key]; 删除 obj[键]; } else if （obj[key] ！== null &&; typeof obj[key] === “object”） { obj[key] = renameKeyObject（obj[key]， oldKey， newKey）; } }); 返回卷; };
