javascript - Discord.js embed countdown

Question

I need some help: How am I able to create a embed that update itself every 2 seconds?

Info: The embed should include a countdown of 3 days. Every two seconds the embed should update itself and goes down to 00:00:00. I would like to use the following method to get the message and update itself:

bot.guilds.cache.get('').channels.cache.get('').messages.fetch('');

Im really new to discord.js development and need some help :D

Answer 1

You can use the setInterval() method to do this. What this does is run a block of code every ___ seconds. Using this, and a variable to store a Unix timestamp of when the timer will finish, we can update a message using the .edit() method, so it shows how much time is left.

bot.on("ready", () => {
    // other code
    const message = bot.guilds.cache.get('').channels.cache.get('').messages.fetch('');
    let timeLeft = INSERT TIMESTAMP HERE;
    setInterval(() => {
        timeLeft -= 2000;
        message.edit(`There is ${timeLeft} time left!`):
    }, 2000)
})
