Codecademy语法错误意外的令牌

Question

所以我正在进行JS代码课程，而且我在摇滚剪刀上做了一件事，而且我已经看过其他主题了，但是我没有错误的分号。我知道。你能告诉我出了什么问题吗？

var compare = function(choice1, choice2){

if(choice1 === choice2){
    return "The result is a tie!";
}else if(choice1 === "rock"){
    if(choice2 === "scissors"){
        return "rock wins";
    }else{
        return "paper wins";
}else if(choice1 === "paper"){
    if(choice2 === "rock"){
        return "paper wins";
    }else{
        return "scissors wins";
    }
}
}
}

Answer 1

看起来你搞砸了大括号：

var compare = function(choice1, choice2){
    if(choice1 === choice2){
        return "The result is a tie!";
    }else if(choice1 === "rock"){
        if(choice2 === "scissors"){
            return "rock wins";
        }else{
            return "paper wins";
        } // this was missing
    }else if(choice1 === "paper"){
        if(choice2 === "rock"){
            return "paper wins";
        }else{
            return "scissors wins";
        }
    }
}

Answer 2

如果出现以下情况，则其他人会跟着其他人：

else{
    return "paper wins";
}else if(choice1 === "paper"){
if(choice2 === "rock"){
    return "paper wins";
}
