我有这个数组，它包含多个数组，其中包含多个对象，正如您所看到的，一些对象具有相同的 pointInTime 值，我想合并具有相同 pointInTime 的对象并连接price 和 priceLevel，像这样：
[
[
{
pointInTime: "2/28/2022",
result: {
price: 48 - 83,
priceLevel: 2 - 2,
},
}
]
]
我使用了 lodash 的 unionBy 方法，但只能得到唯一的方法，我希望将相似的方法混合在一起，就像我展示的那样。
您可以收集按 pointInTime 分组的数组中的所有值。
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);

我有这个数组，它包含多个数组，其中包含多个对象，正如您所看到的，一些对象具有相同的 pointInTime 值，我想合并具有相同 pointInTime 的对象并连接price 和 priceLevel，像这样：
[
[
{
pointInTime: "2/28/2022",
result: {
price: 48 - 83,
priceLevel: 2 - 2,
},
}
]
]
我使用了 lodash 的 unionBy 方法，但只能得到唯一的方法，我希望将相似的方法混合在一起，就像我展示的那样。
您可以收集按 pointInTime 分组的数组中的所有值。
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);
