不同的用户 ID [discord.js]

Question

So I'm working in a discord bot where I want to add different user Ids in a command but now it doesn't work. the code looks like this:

if (message.author.id !== '513773028606476308', '749446086493470751') return message.channel.send("no")

Answer 1

I'm assuming you want a command only to run ONLY for users with specific IDs. Therefore that if statement would be in some kind of function that handles that specific command.. your answer would be to change that if statement to

if (!['513773028606476308', '749446086493470751'].includes(message.author.id)){return message.channel.send("no")}

However, the best solution would be to have an array of these special IDs in the first place like

let allowed=['513773028606476308', '749446086493470751']
if (!allowed.includes(message.author.id)){return message.channel.send("no")}

There's a few things that are contributing to the problem you're seeing here.

The first is that your if statement isn't set up properly. To do what you're looking for, it'd have to look like if (message.author.id.== '513773028606476308' && message.author.id !== '749446086493470751') . While being able to just comma-seperate those values would be a nice feature, it's not currently something you can do in Javascript. You have to explicitly say "if the author ID is not equal to 513773028606476308 and the author ID is not equal to 749446086493470751 " etc.

All that said, just continuously adding IDs on that if statement probably isn't a really good idea. Like commenters have pointed out, structuring this a bit differently would probably result in code that's both more readable and easier to change in the future. You'd do this by putting those user IDs in an array and then checking if the array doesn't contain those IDs, like so:

let admins = ['749446086493470751', '749446086493470751'];
if (!admins.includes(message.author.id)) {
    return message.channel.send("no");
}

This makes your life a little easier down the line for a few reasons:

• If you want to have other commands that only these two users can use, you don't have to copy-paste that big long if block elsewhere, it's fairly simple and easy.
• If you do add another command like this, and then later want to add a third special user, you only have to change your code in one place (the admins array), rather than potentially missing a spot.
