我有這個陣列，它包含多個陣列，其中包含多個物件，正如您所見，其中一些物件具有相同的 pointInTime 值，我想將具有相同 pointInTime 的物件組合起來，并將價格和價格水平與他們，像這樣：

[
    [
       {
        pointInTime: "2/28/2022",
        result: {
        price: 48 - 83,
        priceLevel: 2 - 2,
                },
       }
    ]
]

我使用了 lodash 的unionBy方法，但這只得到了獨特的方法，我希望像我展示的那樣將相似的方法混合在一起。

uj5u.com熱心網友回復：

您可以收集按 . 分組的陣列中的所有值pointInTime。

const
    data = [[{ pointInTime: "2/28/2022", result: { price: 48, priceLevel: 2 } }, { pointInTime: "3/1/2022", result: { price: 48, priceLevel: 2 } }], [{ pointInTime: "2/28/2022", result: { price: 83, priceLevel: 2 } }, { pointInTime: "3/1/2022", result: { price: 83, priceLevel: 2 } }], [{ pointInTime: "2/28/2022", result: { price: 79, priceLevel: 2 } }, { pointInTime: "3/1/2022", result: { price: 79, priceLevel: 2 } }], [{ pointInTime: "2/28/2022", result: { price: 40, priceLevel: 2 } }, { pointInTime: "3/1/2022", result: { price: 40, priceLevel: 2 } }], [{ pointInTime: "2/28/2022", result: { price: 67, priceLevel: 2 } }, { pointInTime: "3/1/2022", result: { price: 67, priceLevel: 2 } }]],
    result = Object.values(data.flat().reduce((r, { result: { price, priceLevel }, ...o }) => {
        r[o.pointInTime] ??= { ...o, result: { price: [], priceLevel: [] } };
        r[o.pointInTime].result.price.push(price);
        r[o.pointInTime].result.priceLevel.push(priceLevel);
        return r;
    }, {}));

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
