Javascript else if不等于语句

所以我在做一个项目，在其中我多次调用一个名为lettpool的数组，它包含字母表中的所有字母。每次调用一个字母时，该字母都会从列表中删除，如果用户再次尝试选择该字母，则会收到一条错误消息。然而，我似乎无法将消息发送到fire。确切的代码是

}

}
    }
        else if (userGuess.match(letters) && userGuess.length === 1) {
    for (var i = 0; i < letterpool.length; i++) {
        if (userGuess !== letterpool){
        document.getElementById("feedback_box").innerHTML= "You allready guess that one there skippy!"
        }
    }
        }
}

}else {
   document.getElementById("feedback_box").innerHTML= 'please enter one letter, numbers need not apply .';
}

所有代码

你认为用户猜测的是什么！==莱特普尔该怎么办？您正在测试字符串和数组是否不相等。@Bergi我想说的是，如果Userguess不等于在莱特普尔中找到的字符，则显示此消息。您的意思是不等于任何字符吗？如果userGuess包含多个字符怎么办？或者userGuess需要与lettpool相同的字符，顺序相同？所有这些都不是问题所在！==接线员有。编写一个帮助函数，以您期望的方式计算此结果。@Bergi I用原始语句修复了代码，验证了它既是一个字母，也是唯一的字母。但是如果“不相等”比较是什么？是的，它是不相等比较。但是lettpool是一个数组，所以您的输入字符串实际上不等于该数组。你的意思是不等于任何一个？
