Having this array:

[{date: Date, value: number}, {date: Date, value: number}, {date: Date, value: number}...]

[{date: Date, value: number}, {date: Date, value: number}, {date: Date, value: number}...]

How can I transform that array into a new one with the following structure using .reduce?:

[[date, date, date...], [value, value, value...]]

[[date, date, date...], [value, value, value...]]

That doesnt look very clean Is that the best way? I was trying to use reduce

reduce returns a new array doesnt it? how would you do it with reduce? it has been a very long time without using reduce so I really do not know how to do it

const output = input.reduce(
    (acc, curr) => {
        return [
            [...acc[0], curr.date],
            [...acc[1], curr.value],
        ];
    },
    [[], []]
);

const output = input.reduce(
    (acc, curr) => {
        return [
            [...acc[0], curr.date],
            [...acc[1], curr.value],
        ];
    },
    [[], []]
);

I got a version working with reduce, but to be honest I don't see anything wrong with the for loop version, it ended up quite similar
