我可以为变量定义任意规则(大于另一个规则),我以后可以在JavaScript中的if/else语句中进行比较吗？

Question

我正在用JavaScript编写一个类似摇滚纸剪刀的游戏.我已经以某种方式工作,但它更像是写出所有的情况,而不是让它做比较.看起来像这样:

var weapons = ["bomb", "knife", "pistol"];


var player = prompt("Choose your weapon: bomb, knife or a pistol?");
console.log("You picked a " + player + ".");

var  = weapons[Math.floor(Math.random() * weapons.length)];
console.log(" picked a " +  + ".");


while (player == ) {
    var player = prompt("You chose " + player + " and he chose " +  + 
    " - the same weapon. Draw is not an option, so " +
    "try again! Pick bomb, knife or pistol.");
    console.log('...');
    var  = weapons[Math.floor(Math.random() * weapons.length)];
    console.log(" picked a " +  + ".")
}

if (player == "bomb" &&  == "knife") 
    console.log( `...`);

else if (player == "bomb" &&  == "pistol")
    console.log(`...`);

else if (player == "knife" &&  == "pistol")
    console.log('...');

else if (player == "knife" &&  == "bomb")
    console.log(`...`);

else if (player == "pistol" &&  == "bomb")
    console.log(`...`);

else if (player == "pistol" &&  == "knife")
    console.log(`...`);

else
    console.log(`...`);

有没有办法将(炸弹>刀&&炸弹<手枪)等规则存储到某个东西中,然后将其传递给if/else进行比较？或者即使可能,我也不应该这样做？

您可以使用具有决策的对象作为树

decisions = {
    bomb: {
        bomb: function () { },
        knife: function () { },
        pistol: function () { }
    }, knife: {
        bomb: function () { },
        knife: function () { },
        pistol: function () { }
    }, pistol: {
        bomb: function () { },
        knife: function () { },
        pistol: function () { }
    }
};
