我想把它变成一个新的 JSON 对象，其中所有内容都按 id 分组（它已经是但我需要数字成为键）然后按 categoryCode 所以结果看起来像这样：
{
'1': {
'555': [{ itemCode: '456'}, { itemCode: '457'}, { itemCode: '458'}]
}
}
有没有一种简单的方法可以使用 lodash 或纯 JavaScript 或一些 NPM 包来做到这一点？这类似于这个问题：JavaScript group data into tree view 2 levels deep 但不同之处在于第三级是对象数组。
解决方案
如果组有必要，您可以采用两个嵌套循环并创建新的对象/数组。
var data = [{ venueId: "10001", items: [{ venueId: "10001", locationId: "14", itemCode: "1604", itemDescription: "Chef Instruction", categoryCode: "28", categoryDescription: "Food Instructions", qty: 0, saleValue: 0, saleDatetime: "0001-01-01T00:00:00", timeToLive: 0 }, { venueId: "10001", locationId: "14", itemCode: "1381", itemDescription: "Meat Lovers Pizza", categoryCode: "48", categoryDescription: "25Fore - Pizza", qty: 0, saleValue: 0, saleDatetime: "0001-01-01T00:00:00", timeToLive: 0 }, { venueId: "10001", locationId: "14", itemCode: "1027", itemDescription: "Sweet Spot Latte Mug", categoryCode: "23", categoryDescription: "Sweet Spot - Coffee/Tea", qty: 0, saleValue: 0, saleDatetime: "0001-01-01T00:00:00", timeToLive: 0 }, { venueId: "10001", locationId: "17", itemCode: "1413", itemDescription: "Garlic Bread", categoryCode: "51", categoryDescription: "25Fore - Starters", qty: 0, saleValue: 0, saleDatetime: "0001-01-01T00:00:00", timeToLive: 0 }, { venueId: "10001", locationId: "17", itemCode: "51", itemDescription: "Cascade Light Schooner", categoryCode: "4", categoryDescription: "Bulk Beer", qty: 0, saleValue: 0, saleDatetime: "0001-01-01T00:00:00", timeToLive: 0 }, { venueId: "10001", locationId: "15", itemCode: "827", itemDescription: "Banrock Station Moscato 1L", categoryCode: "15", categoryDescription: "Wine White", qty: 0, saleValue: 0, saleDatetime: "0001-01-01T00:00:00", timeToLive: 0 }, { venueId: "10001", locationId: "15", itemCode: "1192", itemDescription: "Apple Slice", categoryCode: "31", categoryDescription: "Cafe Gold - Cake Selection", qty: 0, saleValue: 0, saleDatetime: "0001-01-01T00:00:00", timeToLive: 0 }, { venueId: "10001", locationId: "15", itemCode: "301", itemDescription: "Tooheys New 6pk", categoryCode: "4", categoryDescription: "Bulk Beer", qty: 0, saleValue: 0, saleDatetime: "0001-01-01T00:00:00", timeToLive: 0 }, { venueId: "10001", locationId: "12", itemCode: "1036", itemDescription: "Cappuccino 16oz", categoryCode: "23", categoryDescription: "Sweet Spot - Coffee/Tea", qty: 0, saleValue: 0, saleDatetime: "0001-01-01T00:00:00", timeToLive: 0 }, { venueId: "10001", locationId: "12", itemCode: "61", itemDescription: "Great Northern Orig Pint", categoryCode: "4", categoryDescription: "Bulk Beer", qty: 0, saleValue: 0, saleDatetime: "0001-01-01T00:00:00", timeToLive: 0 }, { venueId: "10001", locationId: "12", itemCode: "1232", itemDescription: "Asst.
