如何基于Javascript / Jquery中的多个键对数组项进行分组

我有一个如下的Javascript数组

var data = [{
            "Ticket_id": "239248",
            "Order_Issue": "SAP",
            "Region": "EU",
            "Line_No": "10",
            "Line_Issue": "Qty not available",
            "Serial_Number": "72CEP92"
        },
        {
            "Ticket_id": "239248",
            "Order_Issue": "SAP",
            "Region": "EU",
            "Line_No": "20",
            "Line_Issue": "contact info missing",
            "Serial_Number": "2198IE3"
        }];

我想按多个键对数组进行分组。结果应如下所示：

var data = [{
            "Ticket_id": "239248",
            "Order_Issue": "SAP",
            "Region": "EU",
            "Lines" : [ 
            {"Line_No": "10",
            "Line_Issue": "Qty not available",
            "Serial_Number": "72CEP92"},
            {"Line_No": "20",
            "Line_Issue": "contact info missing",
            "Serial_Number": "2198IE3"}]
        }];

因此，基本上，我将按Ticket_id，Order_Issue和Region分组。我将添加Items子数组，在其中存储所有Line_No，Line_Issue和Serial_Number。

我成功地仅按一个键分组，比如下面的示例Ticket_id。当我向对象添加另一个键时obj[item."Order_Issue] = obj[item."Order_Issue] || [];，分组依据只会在该键上完成，而忽略前一个键。任何建议都请问我在做什么错以及如何获取我想要的确切格式。谢谢。

            "Ticket_id": "239248",
            "Order_Issue": "SAP",
            "Region": "EU",
            "Line_No": "10",
            "Line_Issue": "Qty not available",
            "Serial_Number": "72CEP92"
        },
        {
            "Ticket_id": "239248",
            "Order_Issue": "SAP",
            "Region": "EU",
            "Line_No": "20",
            "Line_Issue": "contact info missing",
            "Serial_Number": "2198IE3"
        },
        {
            "Ticket_id": "239267",
            "Order_Issue": "Online Payment",
            "Region": "EU",
            "Line_No": "10",
            "Line_Issue": "card expired",
            "Serial_Number": "21BBF03"
        }];
        
 var group_Line_No = data.reduce(function (obj, item) {
    obj[item.Ticket_id] = obj[item.Ticket_id] || [];
    obj[item.Ticket_id].push(item.Line_No);
    return obj;
}, {});

console.log(group_Line_No);

var groups = Object.keys(group_Line_No).map(function (key) {
    return {Ticket_id: key, Line_No: group_Line_No[key]};
});

console.log(groups);
