Discord.js random message after x amount of time (Code Correction)

Question

I need to have my discord bot send a random message every 1.5 hours (1 second here for testing) and so far I used the following code but it did not work:

'use strict';

const { Client, MessageEmbed } = require('discord.js');

const client = new Client();

client.on('ready', () => {

console.log(`Logged in to Discord succesfully as ${client.user.tag}!`);

});

var facts = ['Zebra', 'Elephant', 'Goose', 'Lion', 'Turtle', 'Mongoose']

setInterval(function() {

var fact = Math.floor(Math.random() * facts.length)

console.log(facts[fact])

}, 1000) // Changed to 1s for testing

client.on('message', message => {

if (message.content != '101') {

message.channel.send(facts[fact]);

}

});

client.login(process.env.DISCORD_TOKEN);

I really would appreciate it if you helped me out and sorry because I am just a beginner to node.js, e.t.c.

Thanks!

Hi T.K.

It looks like that code will have a bug due to an issue with scope.

Inside your setInterval callback function you've defined a variable "fact," but then you try to reference fact outside of that scope on the line where you write "message.channel.send(facts[fact]);" This should cause a reference error.

You can declare var fact outside the setInterval function, then reassign its value inside the interval, allowing you to have access to fact in the global scope. This should at least solve the reference error.

I'm not sure what other issues you may have in regards to the discord API, but hopefully you find this helpful in improving your knowledge of JavaScript :)
