从函数调用参数

我正在尝试学习javascript,这一课让我创造了一个摇滚,纸张,剪刀游戏。它要求我:

Call your function and pass in userChoice and computerChoice as your two arguments.

我不知道如何传递userChoice和计算机选择。我试过这样做:

console.log(compare + userChoice + computerChoice)

但显然这是不正确的。

我做错了什么?

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 {
         "paper wins";
     }
 } else if (choice1 === "paper") {
     if (choice2 === "rock") {
         return "paper wins";
     } else {
         return "scissors wins";
     }
 } else if (choice1 === "scissors") {
     if (choice2 === "rock") {
         return "rock wins";
     } else {
         return "scissors wins";
     }
 }
}
console.log(compare + userChoice + computerChoice)

你非常接近,参数传递给这样的函数:

compare(userchoice, computerChoice);
