javascript - Codecademy 语法错误 意外标记 else

Question

所以我正在学习 JS codecademy 类(class)，我正在学习石头剪刀布的事情，我也看过其他主题，但据我所知，我没有放错分号。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

看起来你弄乱了大括号:

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";
        }
    }
}
