Chat bot command cooldown

Question

So I'm working on a Discord Bot that uses discord.js, a node.js wrapper for the Discord API. Basically the code works like this:

/*
  A ping pong bot, whenever you send "ping", it replies "pong".
*/

// import the discord.js module
const Discord = require('discord.js');

// create an instance of a Discord Client, and call it bot
const bot = new Discord.Client();

// the token of your bot - https://discordapp.com/developers/applications/me
const token = 'your bot token here';

// create an event listener for messages
bot.on('message', message => {
  // if the message is "ping",
  if (message.content === 'ping') {
    // send "pong" to the same channel.
    message.channel.sendMessage('pong');
  }
});
bot.login(token);

But my question is, how can I make it so that a user can only use the "ping" command with a cooldown of 3 seconds. To do this you would need the user ID, and that would be message.author.id if you were wondering. Thanks in advance.

You could use an array for the "blocked" users. Everytime an user uses the ping command you add the id to the array and use setTimeout(function(){},3000) to delete it again.
