Grouping a dynamic array object and forming a object required

I have a dynamic object something like this

var object = [
    "70669",
    "70669|9436",
    "70669|8353",
    "70669|8914",
    "70669|9522",
    "70669|8422",
    "70669|9639"
    ]

My expected output is something like this

[{
    stdSizeCode: [9436, 8353, 8914, 9522, 8422, 9639]
    productHierSk: 70669
}]

I have tried to looking into this link and did not work the way that is expected. Can someone please suggest

>Solution :

You could group by with an object and get the values as result.

const
    data = ["70669", "70669|9436", "70669|8353", "70669|8914", "70669|9522", "70669|8422", "70669|9639"],
    result = Object.values(data.reduce((r, s) => {
        const [productHierSk, code] = s.split('|').map(Number);
        r[productHierSk] ??= { stdSizeCode: [], productHierSk };
        if (value !== undefined) r[productHierSk].stdSizeCode.push(code);
        return r;
    }, []));

console.log(result);
