如何在 typescript 中将一些属性从一个数组添加到另一个数组

Question

我想循环并将属性从一个数组添加到另一个数组：Array1：

const users = [
   {
      "id":"112",
      "firstName":"a",
      "lastName":"b",
      "address":[
         {
            "apartment":"1",
            "street":"north"
         }
      ]
   },
   {
      "id":"113",
      "firstName":"e",
      "lastName":"f",
      "address":[
         {
            "apartment":"2",
            "street":"north"
         }
      ]
   },
   {
      "id":"114",
      "firstName":"i",
      "lastName":"j",
      "address":[
         {
            "apartment":"3",
            "street":"south"
         }
      ]
   },
   {
      "id":"1151",
      "firstName":"o",
      "lastName":"p",
      "address":[
         {
            "apartment":"4",
            "street":"west"
         }
      ]
   }
]

所以，我有一个空数组const usersInfo = []我只想在users数组中的usersInfo中添加id和address

我在下面尝试做的事情：

    const result = this.usersInfo.map(item => {
  users.forEach((element) => {
    item.id = element.id,
    item.address = element.address.map(r => {
      return {
        apartment: r.apartment,
        street: r.street
      };
    }),
  });

});

但这会返回一个空数组作为结果。

我需要 output 如下所示

const usersInfo = [
    {
      id: '112',
      address:[{
        apartment:'1',
        street: 'north'
      }]
},
      {
      id: '113',
      address:[{
        apartment:'2',
        street: 'north'
     }]
    },
    {
      id: '114',
      address:[{
        apartment:'3',
        street: 'south'
      }]
    },
    {
      id: '1151',
      address:[{
        apartment:'4',
        street: 'west'
      }]
   }
]

Answer 1

您可以执行以下操作：

const usersInfo = users.map(user => ({id: user.id, address: user.address}))
