Reactnative react native 如何更新倒置平面列表的数组中的项目

以下是我的代码

 response.data.data.map((item, index) => {
                console.log('response',item);
                const itemIndex = dataList.findIndex(v => v.dt3 === item.dt3);
                if (itemIndex > -1) {
                  //update quantity in list if same item is selected more than one time
                  const value = {
                    ds: item.ds,
                    bl: item.bl,
                    mty: item.od_auto.Mty,
                    name: item.customer_name_auto,
                  };
                  dataList.push(value);
                } else {
                  const value = {
                    ds: item.ds,
                    bl: item.bl,
                    mty: item.od_auto.Mty,
                    name: item.customer_name_auto,
                  };
                  dataList.push(item.dt3);
                  for(let i = 0; i<dataList.length; i++){
                    dataList[i] = value;
                  }             
                }
              });

//预期yields

 const DATA = [
    {
    title: '4th April, 2020',
    data: [
      {
    ds: item.ds,
                    bl: item.bl,

                    name: item.customer_name_auto,
    },{

                    bl: item.bl,
                    mty: item.od_auto.Mty,
                    name: item.customer_name_auto,
    }
     ],
    },
    {
    title: '3rd April, 2020',
    data: [

                    name: item.customer_name_auto,
    },{
    ds: item.ds,
                    bl: item.bl,
                    mty: item.od_auto.Mty,
                    name: item.customer_name_auto,
    }
     ],
    },
    {

    data: [
    {

                    bl: item.bl,
                    mty: item.od_auto.Mty,
                    name: item.customer_name_auto,
    },{
    ds: item.ds,
                    bl: item.bl,
                    mty: item.od_auto.Mty,
                    name: item.customer_name_auto,
    }
     ],
    },
    {
    title: '1st April, 2020',
    data: [
     {
    ds: item.ds,
                    bl: item.bl,
                    mty: item.od_auto.Mty,
                    name: item.customer_name_auto,
    },{
    ds: item.ds,
                    bl: item.bl,
                    mty: item.od_auto.Mty,
                    name: item.customer_name_auto,
    }
     ],
    },
    ];

我从Api获取响应以创建倒排扁平列表.在我的响应数组中，数组中的每一项都有Date对象.现在我想将日期相同的项分组到一个数组中.请帮助我排列这些数组项
