JavaScript 解构对象

Question

我有以下对象（数据模型）：

const TimeSheetSchema = mongoose.Schema({
    category: {
        type: String,
        require: true
    },
    duration: {
        start: Date,
        end: Date
    },
    isDeleted: {
        type: Boolean,
        default: false
    }
});

如何解构 timeSheet 对象以便在排序函数中使用字段 "start"？

try {
    const timeSheets = await TimeSheet
        .find({isDeleted: false})
        .sort({start: -1});
    res.json(timeSheets);
} catch (err) {
    console.error(err.message);
    res.status(500).send('Server error');
}

尝试在引号内使用点符号 - https://docs.mongodb.com/manual/reference/method/cursor.sort/#examples

try {
    const timeSheets = await TimeSheet
        .find({isDeleted: false})
        .sort({"duration.start": -1});
    res.json(timeSheets);
} catch (err) {
    console.error(err.message);
    res.status(500).send('Server error');
}
