Javascript 将对象数组分组为特定格式

我有一个如下格式的对象数组：

const arr = [
    {
        parentKey: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringA',
            myKey3: false,
            myKey4: true
        },
        anotherKey: {}
    },
    {
        parentKey: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringA',
            myKey3: true,
            myKey4: false
        },
        anotherKey: {}
    },
    {
        parentKey: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringA',
            myKey3: true,
            myKey4: false
        },
        anotherKey: {}
    },
    {
        parentKey: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringA',
            myKey3: true,
            myKey4: true
        },
        anotherKey: {}
    },
    {
        parentKey: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringB',
            myKey3: true,
            myKey4: true
        },
        anotherKey: {}
    },
    {
        parentKey: {
            myKey1: 'someStringB',
            myKey2: 'anotherStringB',
            myKey3: false,
            myKey4: true
        },
        anotherKey: {}
    }
];

const result = [
    {
        props: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringA',
            myKey3: false,
            myKey4: true
        },
        entries: [
            {
                parentKey: {
                myKey1: 'someStringA',
                myKey2: 'anotherStringA',
                myKey3: false,
                myKey4: true
                },
                anotherKey: {}
            }
        ] 
    },
    {
        props: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringA',
            myKey3: true,
            myKey4: false
        },
        entries: [
            {
                parentKey: {
                myKey1: 'someStringA',
                myKey2: 'anotherStringA',
                myKey3: true,
                myKey4: false
                },
                anotherKey: {}
            },
            {
                parentKey: {
                    myKey1: 'someStringA',
                    myKey2: 'anotherStringA',
                    myKey3: true,
                    myKey4: false
                },
                anotherKey: {}
            }
        ] 
    },
    {
        props: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringA',
            myKey3: true,
            myKey4: true
        },
        entries: [
            {
                parentKey: {
                    myKey1: 'someStringA',
                    myKey2: 'anotherStringA',
                    myKey3: true,
                    myKey4: true
                },
                anotherKey: {}
            }
        ] 
    },
    {
        props: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringB',
            myKey3: true,
            myKey4: true
        },
        entries: [
            {
                parentKey: {
                    myKey1: 'someStringA',
                    myKey2: 'anotherStringB',
                    myKey3: true,
                    myKey4: true
                },
                anotherKey: {}
            }
        ] 
    },
    {
        props: {
            myKey1: 'someStringB',
            myKey2: 'anotherStringB',
            myKey3: false,
            myKey4: true
        },
        entries: [
            {
                parentKey: {
                    myKey1: 'someStringB',
                    myKey2: 'anotherStringB',
                    myKey3: false,
                    myKey4: true
                },
                anotherKey: {}
            }
        ] 
    }
];

我需要得到以下格式的结果：

const arr = [
    {
        parentKey: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringA',
            myKey3: false,
            myKey4: true
        },
        anotherKey: {}
    },
    {
        parentKey: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringA',
            myKey3: true,
            myKey4: false
        },
        anotherKey: {}
    },
    {
        parentKey: {
            myKey1: 'someStringA',
            myKey2: 'anotherStringA',
            myKey3: true,
            myKey4: false
        },
        anotherKey: {}
    },

    {

我正在尝试编写一个函数groupArray，它将根据提供的键数组对对象数组进行分组，例如，

groupArray（arr，['parentKey.myKey1'，'parentKey.myKey2'，'parentKey.myKey3'，'parentKey.myKey4']）

。这是我的密码。所有条目当前都放置在结果数组中，而不进行分组

---

你能告诉我如何修复我的功能吗

您可以使用哈希表对同一组进行分组，并使用函数从对象中获取值，该对象的路径通过嵌套属性

函数组数组（数组，键）{
函数getValue（对象、路径）{
返回路径.split（'..）.reduce（（o，k）=>（o |{}）[k]，对象）；
}
var hash=Object.create（null），
结果=[]；
array.forEach（函数（o）{
var key=keys.map（k=>getValue（o，k））.join（“|”）；
如果（！哈希[键]）{
hash[key]={props:Object.assign（…keys.map（k=>（{[k.split（'.'）.pop（）]：getValue（o，k）}）），条目：[]}；
result.push（散列[键]）
}
hash[key].entries.push（o）；
});
返回结果；
}
var数组=[{parentKey:{myKey1:'sometherstringa'，myKey2:'anotherStringA'，myKey3:false，myKey4:true}，anotherKey:{}，{parentKey:{myKey1:'sometherstringa'，myKey2:'anotherStringA'，myKey3:true，myKey4:false}，anotherKey:{}，{parentKey:{myKey1:'sometherstringa'，myKey2:'anotherStringA'，myKey3:true，myKey4:false}，{parentKey:{myKey1:'someStringA'，myKey2:'anotherStringA'，myKey3:true，myKey4:true}，anotherKey:{}，{parentKey:{myKey1:'someStringA'，myKey2:'anotherStringB'，myKey3:true，myKey4:true}，anotherKey:{}，{parentKey:{myKey1:'someStringB'，myKey2:'anotherStringB'，myKey3:false，myKey4:true}，anotherKey:}，}，
结果=groupArray（数组，['parentKey.myKey1'，'parentKey.myKey2'，'parentKey.myKey3'，'parentKey.myKey4']；

您好，不知道您的意思，您正在尝试将对象分组在一起吗？您提供的结果格式只是重新构造原始列表，没有分组。条目按提供的键分组。如果检查结果，您将看到
结果的第二个对象包含原始数组
arr
中的两个对象。我正在尝试归档一些类似的东西，但没有嵌套。
