I am trying to learn node.js after python and trying to thread an infinitely running process in the background with a 2 minute sleep().

main.js

const TeleBot = require("telebot");
const fun = require('fun.js');

fun(); //function I want to thread

const bot = new TeleBot({
  token: "Bot_Token",
});

bot.on(["/start", "/hello"], (msg) => {
  bot.sendMessage(msg.from.id, `Hello ${msg.chat.username}`);
});

bot.start();

I saw some people using this sleep() function but it didn't work

fun.js

module.exports = async function fun()
{
    while (1) {
        await sleep(10000);
        console.log("I ran");
    }
}

Error: sleep is not defined

So, I tried this

const sleep = (waitTimeInMs) => new Promise(resolve => setTimeout(resolve, waitTimeInMs));
module.exports = async function fun()
{
    while (1) {
        await sleep(10000);
        console.log("I ran");
    }
}

It works but is this a good practice and ok to use? Also, can someone tell me how to use worker-threads for this.
