SlowMode for one person is possible ? discord.js - discord.js

Question

I would like to know if it is possible to do some sort of "SlowMode" for a specific person on Discord.
The reason is that I have a "spammer" friend, and I would like to calm him down with a command that might slow him down when he speaks for "x" secondes.
So I would like to know if this is possible? and if yes, how?
Thank you for your kindness =) (and sorry for this english i use GoogleTraductor)

Here's how I'd do that.
let ratelimits = [];
client.on("message", (msg) => {
// APPLYING RATELIMITS
const appliedRatelimit = ratelimits.find(
(value) =>
value.user === msg.author.id && value.channel === msg.channel.id
);
if (appliedRatelimit) {
// Can they post the message?
const canPostMessage =
msg.createdAt.getTime() - appliedRatelimit.ratelimit >=
appliedRatelimit.lastMessage;
// They can
if (canPostMessage)
return (ratelimits[
ratelimits.indexOf(appliedRatelimit)
].lastMessage = msg.createdAt.getTime());
// They can't
msg.delete({ reason: "Enforcing ratelimit." });
}
// SET RATELIMIT
if (msg.content === "!ratelimit") {
// Checking it's you
if (msg.author.id !== "your id") return msg.reply("You can't do that.");
// You can change these values in function of the received message
const targetedUserId = "whatever id you want";
const targetedChannelId = msg.channel.id;
const msRateLimit = 2000; // 2 seconds
// Delete existant ratelimit if any for this user on this channel
ratelimits = ratelimits.filter(
(value) =>
!(
value.user === targetedUserId &&
value.channel === targetedChannelId
)
);
// Add ratelimit
ratelimits.push({
user: targetedUserId,
channel: targetedChannelId,
ratelimit: msRateLimit,
lastMessage: 0,
});
}
// CLEAR RATELIMITS
if (msg.content === "!clearRatelimits") {
// Checking it's you
if (msg.author.id !== "your id") return msg.reply("You can't do that.");
// Clearing all ratelimits
ratelimits = [];
}
});
