Please describe how to reproduce this issue, and include links to screenshots if possible.

My code:

function myTest(val) {
  var answer = "";
  // 请把你的代码写在这条注释以下
  switch (val){
    case 1 :
      answer = "apple";
      break;
    case 2 :
      answer = "bird";
      break;
    case 3 :
      answer = "cat";
      break;  
    default :
      answer = "stuff";
  }
  
  
  // 请把你的代码写在这条注释以上
  return answer;  
}

// 你可以修改这一行来测试你的代码
myTest(a);
