        // console.log("No data found");
        getData(userid);
    }
    else {
        // console.log(data);
        for(let i=0;i<10;i++){
            console.log(data[0][i],data[1][i],data[2][i],data[3][i],data[4][i].forEach(element => {
                console.log(element)   
            }));
        }
        return;
    }
  } catch (error) {
