映射前按属性对对象数组进行排序

Question

我有一个看起来像这样的数组（它有更多的对象，但是结构相同）：

[
  {
      especiality: "surgery",
      users: [
          {
              id: "182",
              country: "Colombia",
              province: "Bogota",
              telephone: "211112212",
              neighbourhood: "La Santa"
              region: "South",
          },
          {
            id: "182",
            country: "Venezuela",
            province: "Caracas",
            telephone: "322323333",
            region: "North",
        },
        {
          id: "183",
          country: "Brasil",
          telephone: "23232333",
          neighbourhood: "Santos"
          region: "South",
      },
      ]
  },

用户由ID确定，地址由四个属性确定。目前，我有此函数，该函数返回一个通过其ID将所有用户加入的地址：

getGroups = test => {
  return test.map(item => {
     item.groupedUsers = [_.groupBy(item.users, user => [user.id])]
     return item
  })
}

问题是，如果ID相同，我还希望这些地址组成一个单个数组（我需要映射这些元素）。外观应如下图所示：

user: [{id: 182, locations[(if they exist)               
              country: "Colombia",
              province: "Bogota",
              telephone: "211112212",
              neighbourhood: "La Santa"
              region: "South"]}]

关于如何解决这个问题的任何想法？由于我需要考虑可能不存在的值，因此它与重复的问题不同。
