array的对象按对象键进行分组

Question

我已经做了一些迭代，但没有达到预期的效果。在

下面有一对对象数组

const data = [
{
"credit_account_id": "244",
"debit_account_id": null,
"sum": "30.00",
"name": "Bank"
},
{
"credit_account_id": null,
"debit_account_id": "244",
"sum": "110.00",
"name": "Bank"
},
....
]

i want to achieve

[
{   name: "Bank",
account : "244",
debit_account : "30",
credit_account: 110
}
]

Answer 1

const data = [
{
"credit_account_id": "244",
"debit_account_id": null,
"sum": "30.00",
"name": "Bank"
},
{
"credit_account_id": null,
"debit_account_id": "244",
"sum": "110.00",
"name": "Bank"
}
]

const dd = [];
data.map((d) => {
const item = dd.find((x) => x.name === d.name);
if (item) {
if (d.debit_account_id) {
item.debit_account = d.sum;
}
return (item.credit_account = d.sum);
}
const obj = { name: d.name };
if (d.debit_account_id) {
obj.debit_account = d.sum;
obj.ledger_account = d.debit_account_id;
} else {
obj.credit_account = d.sum;
obj.ledger_account = d.credit_account_id;
}
return dd.push(obj);
});

console.log (dd)

[
{   name: "Bank",
account : "244",
debit_account : "30",
credit_account: 110
}
]
