如何比较2个长度数组的对象条目的属性并合并为一个？

Question

我正在尝试通过属性和值来比较 values1 和 values2。如果 name 属性的值相互匹配，我想将属性和值推到 value3.

但我收到此错误：无法读取未定义的属性 'age'

const values1 = [
  { name: 'dog', surname: 'good', skills: 'programming' },
  { name: 'cat', surname: 'soft', skills: 'engineer' },
  { name: 'elephant', surname: 'big', skills: 'programming' }
]

const values2 = [
  { name: 'cat', age: '12' },
  { name: 'elephant', age: '13' },
]

const values3 = values1.map((value1) => {
  return Object.assign(value1, { age: values2.filter(value2 => value2.name === value1.name)[0].age })
})

console.log(values3)

这是我想要的结果return。

{
name: 'cat',
surname: 'soft',
skills: 'engineer'
age: '12'
},
{
name: 'dog',
surname: 'good',
skills: 'programming',
},
{
name: 'elephant',
surname: 'big',
skills: 'programming'
age: '23'
}

Answer 1

你可以这样做：

const values1 = [{
    name: 'dog',
    surname: 'good',
    skills: 'programming'
  },
  {
    name: 'cat',
    surname: 'soft',
    skills: 'engineer'
  },
  {
    name: 'elephant',
    surname: 'big',
    skills: 'programming'
  }
]

const values2 = [{
    name: 'cat',
    age: '12'
  },
  {
    name: 'elephant',
    age: '13'
  },
]

const values3 = values1.map((value1) => {
  const sameObj = values2.find(value2 => value2.name === value1.name);
  if (sameObj) {
    return { ...value1, age: sameObj.age }
  }
  return value1;
});

console.log(values3)
