I am trying to solve this and keep getting stuck. I am currently trying to do this with lodash but open to any solution:
EDIT: I've done many searches and the suggested links are not the desired output
Array structure:
[
{ "date": "2022-03-01", "A": 11549 },
{ "date": "2022-03-01", "B": 4536 }
]
to become
[
{ "date": "2022-03-01", "A": 11549, "B": 4536 },
]
Would this work for you ?
const arr = [
{ date: '2022-03-01', A: 11549 },
{ date: '2022-03-01', B: 4536 },
{ date: '2022-03-01', C: 8000 },
{ date: '2022-03-01', D: 4000, F: 7500 },
{ date: '2022-04-02', A: 4536 },
];
const r = Object.values(arr.reduce((o, curr) => {
if (o[curr.date]) {
for (const entry of Object.entries(curr)) o[curr.date][entry[0]] = entry[1];
} else o[curr.date] = curr;
return o;
}, {}))
console.log(r);
