Javascript 如何将我的许多if语句转换为switch语句？Discord.js

我对JavaScript非常陌生，所以如果这是一个荒谬的问题，我道歉

这是我的密码：

client.on('message', message => {
    if (message.content === '!rule1') {
        message.channel.send('Rule 1: **Don\'t be annoying.**');
    }
    if (message.content === '!rule2') {
        message.channel.send('Rule 2: **Leaving the server during your crypt sentence will result in a permanent ban. 3 strikes and you\'re out.**');
    }
    if (message.content === '!rule3') {
        message.channel.send('Rule 3: **Watch your language.**');
    }
    if (message.content === '!rule4') {
        message.channel.send('Rule 4: **No NSFW content of any kind.**');
    }
    if (message.content === '!rule5') {
        message.channel.send('Rule 5: **No racism, homophobia, or other hate speech is allowed whatsoever.**');
    }
    if (message.content === '!rule6') {
        message.channel.send('Rule 6: **Moderators\' discretion.**');
    }
    if (message.content === '!rule7') {
        message.channel.send('Rule 7: **Don\'t randomly ping roles or people for no reason.**');
    }
    if (message.content === '!rule8') {
        message.channel.send('Rule 8: **No spam allowed whatsoever.** Spam will result in a delete and warn, and a crypt sentence if continued.');
    }
    if (message.content === '!rule9') {
        message.channel.send('Rule 9: Please speak English at all times! Non-English messages are subject to deletion.');
    }
    if (message.content === '!rule10') {
        message.channel.send('Rule 10: **Please avoid talking about triggering topics.**');
    }
    if (message.content === '!rule11') {
        message.channel.send('Rule 11: **Please censor all personally identifiable info from images and text.**');
    }
    if (message.content === '!rule12') {
        message.channel.send('Rule 12: **Please keep bot commands in <#620789282226962464>**.');
    }
    if (message.content === '!rule13') {
        message.channel.send('Rule 13: **Posting gore is an instant deletion of your message(s) and permanent ban.**');
    }
    if (message.content === '!rule14') {
        message.channel.send('Rule 14: **YOU MUST BE 13 YEARS OF AGE OR OLDER TO USE THIS SERVER.**');
    }
    if (message.content === '!rule15') {
        message.channel.send('Rule 15: **Politics are strictly banned from the server.**');
    }
    if (message.content === '!rule16') {
        message.channel.send('Rule 16: **Don\'t name yourself stupid things.**');
    }
    if (message.content === '!rule17') {
        message.channel.send('Rule 17: **No bright flashing media of any kind, including emotes.**');
    }
    if (message.content === '!rule18') {
        message.channel.send('Rule 18: **No Gacha edits.**');
    }
    if (message.content === '!rule19') {
        message.channel.send('Rule 19: **Keep conversation civil and appropriate.**');
    }
    if (message.content === '!rule20') {
        message.channel.send('Rule 20: **No edgy, dark or offensive jokes or memes.**');
    }
    if (message.content === '!rule21') {
        message.channel.send('Rule 21: **No threats or considerations of ||self-harm|| or ||suicide|| in the server.**');
    }
    if (message.content === '!rule22') {
        message.channel.send('Rule 22: **Anything that violates Discord TOS will get you immediately banned.**');
    }
    if (message.content === '!rule23') {
        message.channel.send('Rule 23: **Do not sexualize/ship any of the moderators, or any members of the server for that matter.**');
    }
    if (message.content === '!strikeappeal') {
        message.channel.send('If you would like to appeal a strike, you can DM <@738765589748645908>. Simply explain why you got that strike, why you think it should be removed, and apologize.');
    }
});

我想当我说这个代码看起来很长很凌乱时，你可以同意我的说法。有没有办法缩短这个代码？我不知道如何把它转换成switch语句之类的东西。提前感谢

2个选项：

将除第一个if语句之外的所有if语句更改为else if 这几乎与开关相同，只需最少的调整 阅读switch语句的工作原理

备注：不要忘记案例结束时的中断，否则下一个案例也会执行。

正如@Andreas所建议的，将您的规则放入一个对象中，然后使用一些通用代码来提取相应的规则

常量规则={ “！rule1”：“规则1:*别那么烦人。**”， “！rule2'：”规则2:*在你被判入狱期间离开服务器将导致永久禁令。3次罢工，你就出局了。**” }; //等 client.on'message'，message=>{ const ruleText=规则[message.content]； 如果规则文本{ message.channel.sendruleText； }否则{ //正常信息 }

---

}; 我已经修改了您的代码，以减少重复部分，并使生成新命令和添加新规则变得更容易。但是，不要键入像这样的内容！规则3，你必须打字！规则3
