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
}

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 };

您可以将工作包装在一个函数中，并将其分配给Object原型。也许可以使用流畅的界面样式使多个重命名流动。

Object.prototype.renameProperty = function (oldName, newName) {
     // Do nothing if the names are the same
     if (oldName === newName) {
         return this;
     }
    // Check for the old property name to avoid a ReferenceError in strict mode.
    if (this.hasOwnProperty(oldName)) {
        this[newName] = this[oldName];
        delete this[oldName];
    }
    return this;
};

ECMAScript 5 Specific

我希望语法不是这么复杂，但它肯定是很好的有更多的控制。

Object.defineProperty(
    Object.prototype, 
    'renameProperty',
    {
        writable : false, // Cannot alter this property
        enumerable : false, // Will not show up in a for-in loop.
        configurable : false, // Cannot be deleted via the delete operator
        value : function (oldName, newName) {
            // Do nothing if the names are the same
            if (oldName === newName) {
                return this;
            }
            // Check for the old property name to 
            // avoid a ReferenceError in strict mode.
            if (this.hasOwnProperty(oldName)) {
                this[newName] = this[oldName];
                delete this[oldName];
            }
            return this;
        }
    }
);

重命名对象键的另一种方法:

让我们考虑这个对象:

let obj = {"name": "John", "id": 1, "last_name": "Doe"}

让我们重命名name key为first_name:

let { name: first_name, ...rest } = obj;
obj = { first_name, ...rest }

现在对象是:

{"first_name": "John", "id": 1, "last_name": "Doe"}

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}

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; };
