将数组拆分为动态组[关闭]

Question

我正在尝试根据 size 属性将以下数组拆分为块：

[
    { size:6, value:1 },
    { size:6, value:2 },
    { size:12, value:3 },
    { size:6, value:4 },
    { size:6, value:5 }
]

这个想法是将数组分成 2 个组，但如果数组中的一个项目的大小为 6，则该组必须只有 1 个项目。

所以理想情况下，我希望数组在运行拆分函数后如下所示：

[
    [
        { size: 6, value: 1 },
        { size: 6, value: 2 }
    ],
    [
        { size: 12, value: 3 },
    ]
    [
        { size: 6, value: 4 },
        { size: 6, value: 5 }
    ]
]

据我了解！！

const chunksArray = (arr, chunkSize) => {
    const groups = [];
    let i;
    for (i = 0; i < arr.length; i += chunkSize) {
        groups.push(arr.slice(i, i + chunkSize));
    }
    return groups;
};

const t = [
    { size:6, value:1 },
    { size:6, value:2 },
    { size:12, value:3 },
    { size:6, value:4 },
    { size:6, value:5 }
];

console.log(chunksArray(t, 2));

更新代码 -

var chunksArray = (arr, chunkSize, ownGroup) => {
    let nArray = [];
    nArray.push(arr.splice(0, chunkSize).reduce((nAr, elem, ind) => {
        if (elem[ownGroup.key] == ownGroup.val) {
            nArray.push([elem]);
        } else {
            nAr.push(elem);
        }
        return nAr;
    }, []));

    if (arr.length) nArray = nArray.concat(chunksArray(arr, chunkSize, ownGroup));
    return nArray;
};

const t = [
    { size:6, value:1 },
    { size:6, value:2 },
    { size:12, value:3 },
    { size:6, value:4 },
    { size:6, value:5 },
    { size:6, value:6 }
];
var ownGroup = {key:'size',val:12};
console.log(chunksArray(t, 2, ownGroup));
