Tell us what’s happening:
Describe your issue in detail here.
My code is not working. But I think I’ve done it right way.

  **Your code so far**

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


// Only change code above this line
return answer;
}
switchOfStuff("a");
switchOfStuff("b");
switchOfStuff("c");
switchOfStuff("d");
switchOfStuff(4);
