如何发出命令来回复某个用户 ID？

Question

I'm setting up a whitelist and I want to use discord user IDs to use as a whitelist. I'm wondering if there is a way to make a command only work for certain user IDs?

I've tried many different methods from my own knowledge and other help forums with no luck.

const userId = message.guild.members.find(m => m.id === "212277222248022016");
if(!message.author === userId) {
    message.author.send("Whitelisted")
}else{
    message.author.send("Not whitelisted")
}

I wanted the user ID 212277222248022016 to get a dm saying "Whitelisted" but I always end up getting the dm "Not whitelisted".

---

I figured out the fix for this issue in case anyone comes across this thread and wants to know:

const userId = client.users.get("id here");
if (message.author === userId) {
    message.author.send("Whitelisted")
} else {
    message.author.send("Not whitelisted")
}

Answer 1

Remove the !

const userId = message.guild.members.find(m => m.id === "212277222248022016");
if (message.author === userId) {
message.author.send("Whitelisted")
} else {
message.author.send("Not whitelisted")
}

Your number is too large to be 'held' correctly:

console.log(212277222248022016); --> 212277222248022000
