Tell us what’s happening:

Your code so far


function switchOfStuff(val) {
  var answer = "";
  // Only change code below this line
  switch (val) {
    case a:
    "apple";
    break;
   case "b":
    bird;
    break;
    case "c":
    cat;
    break;
    default "d":
    stuff;
    break;
     
  }
  
  
  // Only change code above this line  
  return answer;  
}

// Change this value to test
switchOfStuff(1);
