如何仅获取对象值的第一个单词

我有一个这样的对象数组：

const customers = [
    {
        customer_name: 'Negan Lucille', 
        customer_age: 45, 
        customer_weapon: 'Bat',
        customer_email: '[email protected]',
        customer_city: 'Washington' 
    },
    {
        customer_name: 'Daryl Dixon', 
        customer_age: 41, 
        customer_weapon: 'Crossbow',
        customer_email: '[email protected]',
        customer_city: 'Atlanta' 
    },
    {
        customer_name: 'Rick Grimes', 
        customer_age: 45, 
        customer_weapon: 'Magnum 357',
        customer_email: '[email protected]',
        customer_city: 'King County' 
    },
];

并且我想将customer_name名字和姓氏分开，因此名字应保留在其中customer_name，姓氏应放在新创建的property中customer_last_name。我也有newKeys数组，我将用来替换customers对象中的当前键，如下所示：

const newKeys = [
   'firstname',
   'lastname',
   'age',
   'weapon',
   'email',
   'city'
]

let newCustomers = customers.map(obj => 
    Object.values(obj).reduce((acc, cur, i) => { 
       acc[newKeys[i]] = cur; 
       return acc; }, {}));

并且新数组应如下所示：

customers = [
  {
    firstname: 'Negan',
    lastname: 'Lucille', 
    age: 45, 
    weapon: 'Bat',
    email: '[email protected]',
    city: 'Washington' 
  },
  {
    firstname: 'Daryl', 
    lastname: 'Dixon',
    age: 41, 
    weapon: 'Crossbow',
    email: '[email protected]',
    city: 'Atlanta' 
  },
  {
    firstname: 'Rick', 
    lastname: 'Grimes',
    age: 45, 
    weapon: 'Magnum 357',
    email: '[email protected]',
    city: 'King County' 
  },
]

做这个的最好方式是什么？一个例子，将不胜感激！

我曾经摔过一只熊。

使用split()打破了名称，添加新的特性，然后删除旧属性。

const customers = [
    {
        customer_name: 'Negan Lucille', 
        customer_age: 45, 
        customer_weapon: 'Bat',
        customer_email: '[email protected]',
        customer_city: 'Washington' 
    },
    {
        customer_name: 'Daryl Dixon', 
        customer_age: 41, 
        customer_weapon: 'Crossbow',
        customer_email: '[email protected]',
        customer_city: 'Atlanta' 
    },
    {
        customer_name: 'Rick Grimes', 
        customer_age: 45, 
        customer_weapon: 'Magnum 357',
        customer_email: '[email protected]',
        customer_city: 'King County' 
    },
];

const refactored = customers.map(customer=>{
  var [firstname, lastname] = customer.customer_name.split(/\s/);
  return {
    firstname, lastname,
    age: customer.customer_age,
    weapon: customer.customer_weapon,
    email: customer.customer_email,
    city: customer.customer_city
  }
});

console.log(refactored);
