Как правильно объединить объекты?

Question

[lookingfor2]

Есть объекты такого вида.

[
{
        "user_id": 3,
        "json_build_object": {
            "bank_props": {
                "id": 5,
                "user_id": 3,
                "organization": "4049725573",
                "individual_external_id": "951ac602-55e3-4c44-b35d-560da614052b",
                "individual_guid": "951ac602-55e3-4c44-b35d-560da614052b",

           
            },
            "settlements": {
                "id": 5,
                "user_id": 3,
                "organization": "2466557538",
                "individual_external_id": "951ac602-55e3-4c44-b35d-560da614052b",
                "individual_guid": "951ac602-55e3-4c44-b35d-560da614052b",
             
            }
        }
    },
    {
        "user_id": 3,
        "json_build_object": {
            "bank_props": {
                "id": 5,
                "user_id": 3,
                "organization": "4049725573",
                "individual_external_id": "951ac602-55e3-4c44-b35d-560da614052b",
                "individual_guid": "951ac602-55e3-4c44-b35d-560da614052b",
              
            },
            "settlements": {
                "id": 6,
                "user_id": 3,
                "organization": "3198309645",
                "individual_external_id": "951ac602-55e3-4c44-b35d-560da614052b",
                "individual_guid": "951ac602-55e3-4c44-b35d-560da614052b",
       
            }
        }
    },
]

Как их объедденить, чтобы на выходе получился объект такого выида

{
  "bank_props": [
    {
      "id": 5,
                "user_id": 3,
                "organization": "4049725573",
                "individual_external_id": "951ac602-55e3-4c44-b35d-560da614052b",
                "individual_guid": "951ac602-55e3-4c44-b35d-560da614052b",
       
    }
  ],
  "settlements": [
     {
                "id": 6,
                "user_id": 3,
                "organization": "3198309645",
                "individual_external_id": "951ac602-55e3-4c44-b35d-560da614052b",
                "individual_guid": "951ac602-55e3-4c44-b35d-560da614052b",
            
            },
 {
                "id": 5,
                "user_id": 3,
                "organization": "2466557538",
                "individual_external_id": "951ac602-55e3-4c44-b35d-560da614052b",
                "individual_guid": "951ac602-55e3-4c44-b35d-560da614052b",
    
            }
  ]
}

Answer 1

[Rsa97]

const temp = data.reduce(
  (acc, cur) => {
    acc.bank_props[cur.bank_props.id] = cur.bank_props;
    acc.settlements[cur.bank_props.id] = cur.settlements;
    return acc;
  },
  { bank_props: {}, settlements: {} }
);
const result = {
  bank_props: Object.values(temp.bank_props),
  settlements: Object.values(temp.settlements),
};

Answer 2

[0xD34F]

arr.reduce((acc, n) => (
  Object.entries(n.json_build_object).forEach(([ k, v ]) => {
    (acc[k] ??= []).find(m => m.id === v.id) || acc[k].push(v);
  }),
  acc
), {})

Как красиво за 6 строк.
Подскажите пожалуйста.
Я немного неправильно описал то что мне нужно.
Суть в том, объекты который повторяются должны объеденять именно settlements

<b>// Изначальный объект</b>
{
        "user_id": 2,
        "json_build_object": {
            "bank_props": {
