Your code so far

let count = 0;

function cc(card) {
  // Only change code below this line
    case 2: case 3:case 4:case 5:case 6: return count+=1;break

    case 10:case "J": case "Q":case "K":case "A": return count-=1;break;}
    if(count<=0){return count+" "+ "Hold"}
    else{ return count + " "+"Bet"}
  // Only change code above this line

cc(10); cc("J"); cc("Q"); cc("K"); cc("A");
