        const member=10;
        const m = 10;
        const  n = 1;
        let arr = new Array(m);
        for (var i = 0; i < m; i++) {
          arr[i] = new Array(n);
          for (var j = 0; j < i+1; j++) {
          arr[j] = "꽝";
          }
        }

      const randomValue = Math.floor(Math.random() * 10 + 1);
      console.log(randomValue);

       arr.splice(randomValue, 1, "당첨");

      console.log(arr)

          for(var r=0;r<member+1;r++){
                      if(arr[r] ==  "당첨"){

                    		  	console.log('당첨');

                  }  }
