javascript - 如何在控制台中显示 ROCK、PAPER、SCISSOR GAME Javascript 的结果

Question

我目前被javascript中的石头、纸、剪刀游戏困住了。我需要在控制台中显示如下内容： 计算机选择：“Rock” 用户选择：“Paper” 用户获胜！

如何在下面的代码中实现这一点。

                let userSelection = userPlay();
        function userPlay() {
                let random = ["rock", "paper", "scissors"];
            return random[Math.floor(Math.random() * 3)];
        }
        let computerSelection = computerPlay();

        function computerPlay() { //computer generates a random answer.
            let random = ["rock", "paper", "scissors"];
            return random[Math.floor(Math.random() * 3)];

        }
        function playRound(playerSelection, computerSelection) { //plays a round of the game.
            if (playerSelection === "rock") {
                if (computerSelection === "rock") {
                    return "Draw!";
                } else if (computerSelection === "paper") {
                    return "Computer wins!";
                } else {
                    return "User wins!";
                }
            } else if (playerSelection === "paper") {
                if (computerSelection === "rock") {
                    return "User wins!";
                } else if (computerSelection === "paper") {
                    return "Draw!";
                } else {
                    return "Computer wins!";
                }
            } else {
                if (computerSelection === "rock") {
                    return "Computer wins!";
                } else if (computerSelection === "paper") {
                    return "User wins!";
                } else {
                    return "Draw!";
                }
            }
        }
                
        console.log(playRound(userPlay, computerSelection));

我已经交换了函数调用的位置以获得更好的可读性。想法是将每个函数调用的结果存储到一个变量中并打印出来。

        function userPlay() {
                let random = ["rock", "paper", "scissors"];
            return random[Math.floor(Math.random() * 3)];
        }
        function computerPlay() { //computer generates a random answer.
            let random = ["rock", "paper", "scissors"];
            return random[Math.floor(Math.random() * 3)];

        }
        function playRound(playerSelection, computerSelection) { //plays a round of the game.
            if (playerSelection === "rock") {
                if (computerSelection === "rock") {
                    return "Draw!";
                } else if (computerSelection === "paper") {
                    return "Computer wins!";
                } else {
                    return "User wins!";
                }
            } else if (playerSelection === "paper") {
                if (computerSelection === "rock") {
                    return "User wins!";
                } else if (computerSelection === "paper") {
                    return "Draw!";
                } else {
                    return "Computer wins!";
                }
            } else {
                if (computerSelection === "rock") {
                    return "Computer wins!";
                } else if (computerSelection === "paper") {
                    return "User wins!";
                } else {
                    return "Draw!";
                }
            }
        }
        
        var userChoice = userPlay();
        var computerSelection = computerPlay();
        var result = playRound(userChoice, computerSelection)
        console.log("user's choice", userChoice);
        console.log("computer's choice", computerSelection);
        console.log("Result is", result);
