Discord Bot Responds Only to a Specific User's Messages

I’m looking for a solution to configure my Discord bot so that it automatically responds only when a particular user sends a message. The bot should identify this user by their unique identifier, which has been intentionally anonymized for demonstration purposes. Below is an updated code sample that implements this behavior:

const specialUserID = "9876543210";

bot.on("messageCreate", (msg) => {
    if (msg.author.id === specialUserID) {
        msg.reply("Hello, special user!");
    }
});

I need any guidance or suggestions on refining this approach, as my goal is to have a bot that exclusively interacts with this designated individual. Your advice on improving this setup would be greatly appreciated.

hey, your code looks fine. you might wanna also check if msg.author.bot isnt true so it doesnt accidentally trigger on bot messages. i thnk its enough for your needs anyway.
