How can I transform the next object array?

I have like 1 hour trying to do the next exercice, so I get looked and I was wondering If someone can help me with this.

Here is the array that I get from the Database Base Array Image

let response =
[{
    "name": "October : 2019",
    "userName": "Katherine Diaz",
    "newCases": 875,
    "recover": 8
  },
  {
    "name": "December : 2019",
    "userName": "Katherine Diaz",
    "newCases": 503,
    "recover": 38
  },
  {
    "name": "November : 2019",
    "userName": "Katherine Diaz",
    "newCases": 227,
    "recover": 14
  },
  {
    "name": "November : 2019",
    "userName": "Belyini Cabral",
    "newCases": 19,
    "recover": 14
  },
  {
    "name": "January : 2020",
    "userName": "Katherine Diaz",
    "newCases": 272,
    "recover": 123
  },
  {
    "name": "October : 2019",
    "userName": "Belyini Cabral",
    "newCases": 287,
    "recover": 1
  },
  {
    "name": "October : 2019",
    "userName": "N/A",
    "newCases": 3,
    "recover": 0
  },
  {
    "name": "January : 2020",
    "userName": "Mercedes Perez",
    "newCases": 65,
    "recover": 0
  },
  {
    "name": "February : 2020",
    "userName": "N/A",
    "newCases": 76,
    "recover": 0
  },
  {
    "name": "December : 2019",
    "userName": "N/A",
    "newCases": 136,
    "recover": 0
  },
  {
    "name": "November : 2019",
    "userName": "Mercedes Perez",
    "newCases": 15,
    "recover": 0
  },
  {
    "name": "January : 2020",
    "userName": "N/A",
    "newCases": 299,
    "recover": 0
  },
  {
    "name": "December : 2019",
    "userName": "Mercedes Perez",
    "newCases": 44,
    "recover": 0
  },
  {
    "name": "October : 2019",
    "userName": "Mercedes Perez",
    "newCases": 323,
    "recover": 0
  },
  {
    "name": "December : 2019",
    "userName": "Belyini Cabral",
    "newCases": 0,
    "recover": 11
  },
  {
    "name": "January : 2020",
    "userName": "Belyini Cabral",
    "newCases": 0,
    "recover": 11
  },
  {
    "name": "February : 2020",
    "userName": "Mercedes Perez",
    "newCases": 0,
    "recover": 20
  },
  {
    "name": "February : 2020",
    "userName": "Belyini Cabral",
    "newCases": 0,
    "recover": 9
  },
  {
    "name": "February : 2020",
    "userName": "Katherine Diaz",
    "newCases": 0,
    "recover": 43
  }
]

I would like to have like this... I have some (Math.round...) functions just to generate random data to test with a dashboard that I want to fill.

            }
        ];

As I see It, it's a little be advanced for me, I think I need more knowledge of data structures in this language, don't need to tell me the whole solution just where to start and some steps.
