Automatic Slowmode Discord.js - discord.js

Question

I've been trying to create a system that automatically sets the slowmode in a channel to a certain amount depending on how many messages have been sent. Lua is my primary language, and not Node.js, therefore I'm having quite a bit of trouble as to how I would go about this. If anyone had any suggestions, please let me know.

Two ways to go about it:
Use discord.js's <TextChannel>.setRateLimitPerUser(number)
https://discord.js.org/#/docs/main/stable/class/TextChannel?scrollTo=setRateLimitPerUser
Not sure if this actually does what you want though, the other option is creating a session storage of the text channels msgCount and compare it to time, i found setRateLimitPerUser in the middle of writing the code so didn't finish it, be here's a start:
const { Client, Collection } = require("discord.js");
const client = new Client();
client.slowdown = new Collection();
client.on("message", msg => {
const id = msg.channel.id;
const attempt = client.slowdown.get(id);
//4 messages at most per second
const ratio = 4;
//look at last how many seconds
const timeSpace = 5;
//TODO: check if channel already has cooldown
if (attempt) {
attempt.msgCount++;
const currentTime = Date.now();
const timePassed = (currentTime - attempt.time) / 1000;
if (attempt.msgCount >= ratio && attempt.msgCount / timePassed >= ratio) {
//setCoolDown
}
if (timePassed >= timeSpace) {
attempt.time = currentTime;
attempt.msgCount = 0;
}
} else {
client.slowdown.set(id, {
time: Date.now(),
msgCount: 1
});
}
});
