代码学院的石头剪刀

Question

我正在学习如何在www.codeacademy.com上在线使用javascript，我制作了这款游戏，你可以用电脑玩石头剪刀。每次我尝试运行它时，我都会遇到SyntaxError: Unexpected end of script的问题，但我找不到问题。

var userChoice = prompt("Do you choose rock, paper or scissors?");
var computerChoice = Math.random();
if (computerChoice < 0.34) {
	computerChoice = "rock";
} else if(computerChoice <= 0.67) {
	computerChoice = "paper";
} else {
	computerChoice = "scissors";
} 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 {
            return "paper wins";
        }
    }
    else if(choice1 === "paper"){
        if(choice2 === "rock"){
            return "paper wins";
        }
        else {
            "scissors wins";
        }
    }
    else if(choice1 === "scissors"){
        if(choice2 === "rock"){
            return "rock wins";
        }
        else {
        "scissors wins";
    }
    
console.log(compare(userChoice,computerChoice)

Answer 1

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

您缺少最后两个括号。
