How to make output of nested array

[sluxzer]

Hi There,

I have a group of array below that I would like to transform

I want the grouping key included,

  "success": true,
  "code": "200",
  "message": "OK",
data: {
    "08 December": {
        [
            id: 1,
            name: 'John',
            status: 'Active'
        ],
        [
            id: 2,
            name: 'John',
            status: 'Active'
        ],
    },
    "09 December": {
        [
            id: 3,
            name: 'John',
            status: 'Active'
        ]
    }
}

currently, I can only get this without the parent of the array:

{
    "success": true,
    "code": "200",
    "message": "OK",
    "data": [
        [
            {
                "id": 6,
                "status": "Complete",
                "name": "Vega Punk"
            },
            {
                "id": 7,
                "status": "Complete",
                "name": "Vega Punk"
            }
        ],
        [
            {
                "id": 8,
                "status": "Complete",
                "name": "Vega Punk"
            }
        ]
    ]
}

here is my code

and is it possible to custom the child? currently I just passing the whole array

I just don't know the keyword how to implement this, I hope you understand

Thank you.
