数组根据某个字段分类

                    const allObj = value.data;
                    const preResult = {};
                    allObj.forEach(obj => {
                        preResult[obj.dictTypeCode] = preResult[obj.dictTypeCode] ? [...preResult[obj.dictTypeCode], obj] : [obj];
                    });
                    const result = Object.values(preResult);
                    console.log(123, result);
