javascript - Discord.js - Is there a method for discord bots to recursively ask questions? Like a form filler bot?

Question

I've written some code down below. My main experience coding is with Python, but I got hooked on a discord.js tutorial and decided to give discord bot coding a try (I know that there's a Python option, but I've already invested a lot of time into this, so unless if it's not feasible, then I will most likely not switch over). I'm still taking a while to get the concept of async/await, hopefully I've applied it correctly in the code. It currently works just asking one question, but I can't seem to continue the operation, even though the counter seems to add fine. I was thinking of a recursive solution, but whenever I do a while loop or a recursion function it still starts on the first question again either way. My main concerns would be whether or not I'm going in a path that can get me to ask multiple questions.

---

tl;dr: The code I've written down below allows the bot to record one response, but when I try to make it repeat using a continuous recursive function, the code just starts back at question 1.

const Discord = require('discord.js');
const client = new Discord.Client();
const token = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';

client.login(token);

const quiz = require('./q.json');
var num = 0;
var item = quiz[num];
var messg = "";
//var line = []; ignore this, this is for recording the responses onto a different application later

client.on('message', async message => {
    if (message.author.bot) return;

    if (message.content === '!test') {
        collec(message);
    }
})

async function collec(message) {
    message.reply(item.question);
    //checks to see if the author that used commmand is the same + if it's an option
    //isPossibleOption() = just constantly gets rid of one element until it fits w/ criteria
    const filter = m => m.author.id === message.author.id && isPossibleOption(m.content, item.answers);

        var collector = new Discord.MessageCollector(message.channel, filter, { max: 1 });

        collector.on("collect", async msg => {
            messg = msg.content;
            //await recordAnswer(messg, num); record it onto google sheets / check for q
            message.channel.send('Next question!');
            nextQ();
        })

        collector.on("end", collected => {});
}

async function isPossibleOption (message, file) {
    var i;
    for (i = 0; i < file.length; i++) {
        if (message.toLowerCase() == file[i]) {
            return true;
        }
    }
    return false;
}

function nextQ () {
    num++;
    item = quiz[num];
}

Message collectors is more of an umbrella term, there are multiple ways to do this in Discord.js. Check out the docs here for more information. To record multiple answers from a user input, your code should look similar to this:

message.channel.send("Please enter an animal:").then(() => {     

  const filter = (user) => {
    return user.author.id === message.author.id && !user.bot  // do not respond to bots, and only respond to the user that called the command
  };

  message.channel.awaitMessages(filter, { max: 1, time: 15000, errors: ['time'] })
      .then(collected => {
        
      // collected is an object created by the awaitmessages event, I will put some dummy code here

      if (collected.content === 'dinosaur') {
        message.channel.send(':white_check_mark: Dinosaur')
      }

      message.channel.send(':white_check_mark:').then(() => {

            message.channel.send("Please enter an animal:").then(() => {                  

              message.channel.awaitMessages(filter, { max: 1, time: 15000, errors: ['time'] }) //the ['time'] parameter is declaring what the awaitMessages depends upon
                  .then(collected => {                                                         // it can also be ['idle'] and a few more, but we need ['time']
                      
                      if (collected.content === 'puppy') {
                        message.channel.send(':white_check_mark: Puppy :dog:')
                      }
                      message.channel.send(':white_check_mark:')
                  });
            });
        });
    });
});

Please let me know if you have any questions. If you are using a DB, simply put the DB write code in the final .then(collected =>) statement
