Предполагая, что у меня есть этот набор данных:

                "CCALENDAR_MONTH": "02/2020",
                "CCALENDAR_WEEK": "09/2020",
                "CEMPLOYEE": "EXT011",
                "KCGROSS_CAPACITY": "8.00000000000000",
                "KCVACATION": "0.00000000000000",
                "UCGROSS_CAPACITY": "HUR",
                "UCVACATION": "HUR"
            }]

Я хотел бы сначала сгруппировать и связать их по ID сотрудника CEMPLOYEE: 

    let e = _.chain(data.d.results)
                    // Group the elements of the result based on `CEMPLOYEE` property
                    .groupBy("CEMPLOYEE")
                    // `key` is group's name (CEMPLOYEE), `value` is the array of objects
                    .map((value, key) => ({
                        Emp: key,
                        Capacity: value
                    })).value();

Как и ожидалось , Я получил желаемый первый результат, например: 

Emp: "E1001"
Capacity: (62) [{…}, {…}, {…}, {…}, {…}]
__proto__: Object

Теперь, когда я застрял, я бы сделал то же самое снова в моем узле Capacity,

Что я пытаюсь чтобы достичь, и мой конечный желаемый результат будет выглядеть следующим образом: 

Emp: "E1001"
Capacity: (62) [
Week: "09/2020"
CapacityPerWeek: (5) [{…}, {…}, {…}, {…}, {…}

etc...
]
__proto__: Object

Итак, я попытался: 

    let e = _.chain(data.d.results)
                // Group the elements of the result based on `CEMPLOYEE` property
                .groupBy("CEMPLOYEE")
                // `key` is group's name (CEMPLOYEE), `value` is the array of objects
                .map((value, key) => ({
                    Emp: key,
                    Capacity: value
                })).value();
            _.forEach(e, function (capacityItem) {
                capacityItem.ChainedCapacity = _.chain(capacityItem.Capacity)
                    // Group the elements of the result based on `CCALENDAR_WEEK` property
                    .groupBy("CCALENDAR_WEEK")
                    // `key` is group's name (CCALENDAR_WEEK), `value` is the array of objects
                    .map((value, key) => ({
                        Week: key,
                        CapacityPerWeek: value
                    })).value();
            });

Но он дал мне раковый вывод, он излишне зациклен на моих предметах

Как этого добиться без зацикливания?

Не уверен насчет lodash, если вы ищете vanilla JS. Пожалуйста, обратитесь к приведенному ниже коду.
