如何使用node.js在JSON中向数组添加字符串？

I have a discord bot and I want to have an array that has the user ids of people who abuse the volume and music commands so that I can take away their abilities and give them back using commands like !nomusic and !musicback, but I have no idea how I would make it add or remove their ids from an array in the config file. My best guess is to use fs and have it push the member's id into the array, but I have no idea how I would go about doing this (I'm very new to node.js and especially fs, so sorry if this is a really easy thing to do and is really dumb to ask)

我有一个不和谐机器人,我希望有一个阵列,其中有滥用音量和音乐命令的用户ID,这样我就可以拿走他们的能力,并使用像!nomusic和!musicback这样的命令给他们回复,但我有不知道如何在配置文件中添加或删除其数组中的ID。我最好的猜测是使用fs并让它将成员的id推入数组中,但我不知道我将如何做到这一点(我对node.js非常新,特别是fs,很抱歉,如果这是一个真的很容易做,真的很愚蠢的问)

So far this is how far I've gotten(lots of the program not included so it's easier to read)

到目前为止,这是我已经走了多远(很多程序没有包括所以它更容易阅读)

function readNoMusicJSON() {
    return JSON.parse(fs.readFileSync("./nomusic.json"));
}

var badmusicusers = readNoMusicJSON();

function nomusicsfoyou(badmusicusers, userId) {
    return nomusic.concat([userId]);
}

function saveNoMusicFile(badmusicusers) {
    fs.writeFileSync("./nomusic.json");
}
bot.on('message', async message => {
//some code ommited due to lack of importance
var args = message.content.slice(config.prefix.length).trim().split(/ +/g);    
var command = args.shift().toLowerCase();
switch(command){
    case"music":
        if(badmusicusers.find(id=>id == message.author.id)) return;
        // more ommitted code that don't matter
        break;
    case "nomusic":
        let sadmusicboi = message.mentions.members.first();
        badmusicusers = nomusicsfoyou((badmusicusers, sadmusicboi.id));
        saveNoMusicFile(badmusicusers);
        break;
    }
})

Suppose you have a list of bannedUsers in your config bannedUsers.json file.

假设你的config bannedUsers.json文件中有一个bannedUsers列表。

["user-id-1", "user-id-2"]

On Startup of the program, you read the file into a variable:

在程序启动时,您将文件读入变量:

function readBannedUsers() {
    return JSON.parse(fs.readFileSync("./bannedUsers.json"));
}

var bannedUsers = readBannedUser();

Whenever you want to ban a user:

每当您想要禁止用户时:

function banUser(bannedUsers, userId) {
     return bannedUsers.concat([userId]);
}

function saveBannedUsers(bannedUsers) {
     fs.writeFileSync("./bannedUsers.json");
}

bannedUsers = banUser(bannedUsers, "user-3");
saveBannedUsers(bannedUsers);

That's all.
