Javascript 石头，布，剪刀，蜥蜴，斯波克

我不熟悉Java脚本和编码。我试图找出石头、布、剪刀、蜥蜴、斯波克中的一个语法错误，它把我的代码搞乱了。当我编译代码时，代码上写着“SyntaxError:Unexpected token{”，我不知道为什么和在哪里搞砸了。谢谢你的帮助

var userChoice = prompt("Do you choose rock, paper or scissors?");
    var computerChoice = Math.random();
    if (computerChoice <= 0.20) {
        computerChoice = "rock";
    }
    else if (computerChoice <= 0.40) {
        computerChoice = "paper";
    }
    else if (computerChoice <= 0.60) {
        computerChoice = "scissors";
    }
    else if (computerChoice <= 0.80) {
        computerChoice = "lizard";
    }
    else {
        computerChoice = "spock";
    }
    console.log("Computer: " + computerChoice);
    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 if (choice2 === "paper") {
                return "paper wins";
            }
            else if (choice2 === "lizard") {
                return "rock wins";
            }
            else {
                return "spock wins";
            }
        }
        else if (choice1 === "paper") {
            if (choice2 === "rock") {
                return "paper wins";
            }
            else if (choice2 === "scissors") {
                return "scissors win";
            }
            else if (choice2 === "lizard") {
                return "lizard wins";
            }
            else {
                return "paper wins";
            }
        }
        else if (choice1 === "scissors") {
            if (choice2 === "rock") {
                return "rock wins";
            }
            else if (choice2 === "paper") {
                return "scissors win";
            }
            else if (choice2 === "lizard") {
                return "scissors win";
            }
            else {
                return "spock wins";
            }
        }
        else if (choice1 === "lizard") {
            if (choice2 === "rock") {
                return "rock wins";
            }
            else if (choice2 === "scissors") {
                return "scissors win";
            }
            else if (choice2 === "paper") {
                return "lizard wins";
            }
            else {
                return "lizard wins";
            }
        }
        else {
            if (choice2 === "rock") {
                return "spock wins";
            }
            else if (choice2 === "paper") {
                return "paper wins";
            }
            else if (choice2 === "scissors") {
                return "spock nigga wins";
            }
            else {
                return "lizard wins";
            }
        }
    };
    compare(userChoice, computerChoice);

var userChoice=prompt（“您选择石头、布还是剪刀？”）；
var computerChoice=Math.random（）；
如果（computerChoice缺少右括号：
else if（choice2===“剪刀”
这个问题最好继续问下去。在把它移到那里之后，你需要澄清“编译”是什么意思，因为JavaScript通常被解释为JavaScript。此外，大多数错误消息都包括一个发生语法错误的行号。为什么你的第二次返回是
返回“spock nigga wins”
？您错过了大括号，所以，请仔细阅读代码并找到它。我认为语法错误对您来说并不是什么大问题。@OozeMeister code Review不是一个不运行代码的地方。这些问题显然与主题无关。下面是一个非常简洁的JavaScript实现，其中包含一个playabl我可以问一下投票失败的原因吗？
