discord - trying to make a bot that counts members in a voice channel

Question

Please don't comment if think that what I'm asking is stupid. I am completely new to this. I tried searching up solutions but couldn't find helpful ones or ones that a noob in discord.js would understand. Thank you for your help in advance!

const express = require ("express")
var app = require('express')();

app.get("/", (req, res) => {
  res.send("hello hell!")
})

app.listen(3000, () => {
  console.log("Project is ready")
})

let Discord = require("discord.js")
let client = new Discord.Client()

client.on('voiceStateUpdate', (oldVoiceState, newVoiceState) => {

let newUserChannel = newVoiceState.voiceChannel

let oldUserChannel = oldVoiceState.voiceChannel

if(oldUserChannel === undefined && newUserChannel !== undefined) {

// User Joins a voice channel
console.log(client.voiceConnections.size)

} else if(newUserChannel === undefined){

// User leaves a voice channel

console.log(client.voiceConnections.size)

}

})

client.login("token")

repl.it outcome when someone joins Project is ready

console.log(client.voiceConnections.size)
                                    ^
