js处理数组分类

const obj = [
    {
        "groupingType": "1",
        "remark": "梨花带雨",
        "totalRmbMoney": 7,
        "kyeGroupingType": "广州一组"
    },
    {
        "groupingType": "2",
        "remark": "99",
        "totalRmbMoney": 0,
        "kyeGroupingType": "广州二组"
    },
    {
        "groupingType": "2",
        "remark": "重生之我百亿富豪",
        "totalRmbMoney": 66,
        "kyeGroupingType": "广州二组"
    },
    {
        "groupingType": "2",
        "remark": "1",
        "totalRmbMoney": 99,
        "kyeGroupingType": "广州二组"
    },
    {
        "groupingType": "3",
        "remark": "哈韩",
        "totalRmbMoney": 12,
        "kyeGroupingType": "佛山一组"
    },
    {
        "groupingType": "3",
        "remark": "大表姐",
        "totalRmbMoney": 0,
        "kyeGroupingType": "佛山一组"
    },
    {
        "groupingType": "3",
        "remark": "梨花带雨",
        "totalRmbMoney": 0,
        "kyeGroupingType": "佛山一组"
    },
    {
        "groupingType": "4",
        "remark": "666",
        "totalRmbMoney": 0,
        "kyeGroupingType": "广州一组"
    },
    {
        "groupingType": "4",
        "remark": "佛山一个",
        "totalRmbMoney": 0,
        "kyeGroupingType": "广州一组"
    },
    {
        "groupingType": "4",
        "remark": "大表哥",
        "totalRmbMoney": 78,
        "jobType": "1",
        "kyeGroupingType": "广州一组"
    }
]


const groupBy = (array: any, key: any) => {
    return array.reduce((result: any, currentItem: any) => {
      // 使用 key 函数如果有定义，否则直接获取属性值
      const groupKey = typeof key === 'function' ? key(currentItem) : currentItem[key];
   
      // 初始化分类数组
      if (!result[groupKey]) {
        result[groupKey] = [];
      }
      // 将当前项推入分类数组
      result[groupKey].push(currentItem);
   
      return result;
    }, {});
  };


const newobj = groupBy(obj, 'kyeGroupingType')
      console.log('newobj', newobj)

输出结果如图：
