解构嵌套数组

Question

如果我有一个包含嵌套数组的对象数组，我该如何 get/destructure 子数组？例如，如果我想创建一个只有地址对象的新数组怎么办？

const people = [
  {
    name: "Jane",
    address: {
      street: "123 Main St",
      city: "Broadway"
    }
  },
  {
    name: "John",
    address: {
      street: "123 Other St",
      city: "Manhattan"
    }
  }
]

Answer 1

请试试这个

const people = [
  {
    name: "Jane",
    address: {
      street: "123 Main St",
      city: "Broadway"
    }
  },
  {
    name: "John",
    address: {
      street: "123 Other St",
      city: "Manhattan"
    }
  }
]

const address=people.map((item)=>item.address)
console.log(address);
