警报命令对我的javascript代码无效

我一直在尝试在石头剪刀上用javascript制作这个简单的游戏。当我在Microsoft edge和Chrome上打开警报命令时，它不会显示。这是我的密码，我需要帮助

当您执行var compare=function。。。。正在定义一个函数。 所以你需要调用这个函数来得到一个结果。 试着做

这只是一个例子，假设您每次都玩剪刀，首先需要调用函数。因此，最好为调用它指定一个函数名，请尝试以下操作：

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 = toCompare(userChoice, computerChoice);

function toCompare(userChoice, computerChoice){
    if (userChoice === computerChoice){
         alert("The result is a tie!");
    }
    if(userChoice === "rock"){
        if (computerChoice === "scissors"){
            alert("rock wins");
        }
        else{
            alert("paper wins");
        }
    }
    if(userChoice === "paper"){
        if (computerChoice === "rock"){
            alert("paper wins");
        }
        else{
            alert("scissors wins");
        }
    }
    if(userChoice === "scissors"){
        if (computerChoice2 === "paper"){
            alert("scissors wins");
        }
        else{
            alert("rock wins");
        }
    }
};

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 = toCompare(userChoice, computerChoice);

function toCompare(userChoice, computerChoice){
    if (userChoice === computerChoice){
         alert("The result is a tie!");
    }
    if(userChoice === "rock"){
        if (computerChoice === "scissors"){
            alert("rock wins");
        }
        else{
            alert("paper wins");
        }
    }
    if(userChoice === "paper"){
        if (computerChoice === "rock"){
            alert("paper wins");
        }
        else{
            alert("scissors wins");
        }
    }
    if(userChoice === "scissors"){
        if (computerChoice2 === "paper"){
            alert("scissors wins");
        }
        else{
            alert("rock wins");
        }
    }
};
