How to remove a property from an array of objects

need to be removed first _id, usedDays, put two arrays (start and end) into the one and deploy "user" in userId and name.

Have array:

[{
    "_id": "someID",
    "user": {
      "_id": "mongoID",
      "name": "Vasya"
    },
    "usedDays": 1,
    "start": "2021-07-02",
    "end": "2021-07-21"
  },
  {
    "_id": "someID",
    "user": {
      "_id": "mongoID",
      "name": "Ivan"
    },
    "usedDays": 5,
    "start": "2021-08-12",
    "end": "2021-08-22"
  }
]

Need array:

  [{
    "userId": "mongoID",
    "name": "Vasya"
    "partyDate": ["start": "2021-07-02","end": "2021-07-21"]
  },
  {
    "userId": "mongoID",
    "name": "Ivan"
    "partyDate": ["start": "2021-08-12","end": "2021-08-22"]
  }
]

I think Array.map is what you are looking for

array.map((item) => {
    return ({
        userId: item.user._id, 
        name: item.user.name, 
        partyDate: [{start: item.start, end: item.end}]
    })
})
