为什么我的纸张，摇滚，剪刀程序不起作用？

Question

我需要使用大写字母吗？

var userChoice=prompt("Do you choose rock, paper or scissors?");
var computerChoice=Math.random();
if (computerChoice>0 && computerChoice<0.33)
   {
     computrChoice=("rock");
   }
else if (computerChoice>0.34 && computerChoice<0.66)
    {
      computerChoice=("paper");
    }
else{computerChoice=("scissors");}
    console.log(computerChoice);

if (computerChoice>0 && computerChoice<0.33)
   {
     computrChoice=("rock");        <<---- you have spell error here
   }
