title: How do you code a purge command
body: <p>So I have been search far and wide over the internet, trying to find a possible way to make a purge command. Now I have found quite a lot of different ways to make one, but none of them either suited me in the way I wanted, or simply worked for me.
  SO to start off, here is my code</p>
  
  <pre><code>const Discord = require("discord.js"); // use discord.js
  
  const BOT_TOKEN = "secret bot token :)" // bot's token
  const PREFIX = "*" // bot's prefix
  
  var eightball = [ // sets the answers to an eightball
      "yes!",
      "no...",
      "maybe?",
      "probably",
      "I don't think so.",
      "never!",
      "you can try...",
      "up to you!",
  ]
  
  var bot = new Discord.Client(); // sets Discord.Client to bot
  
  bot.on("ready", function() { // when the bot starts up, set its game to Use *help and tell the console "Booted up!"
      bot.user.setGame("Use *info") // sets the game the bot is playing
      console.log("Booted up!") // messages the console Booted up!
  });
  
  bot.on("message", function(message) { // when a message is sent
      if (message.author.equals(bot.user)) return; // if the message is sent by a bot, ignore
  
      if (!message.content.startsWith(PREFIX)) return; // if the message doesn't contain PREFIX (*), then ignore
  
      var args = message.content.substring(PREFIX.length).split(" "); // removes the prefix from the message
      var command = args[0].toLowerCase(); // sets the command to lowercase (making it incase sensitive)
      var mutedrole = message.guild.roles.find("name", "muted");
  
      if (command == "help") { // creates a command *help
          var embedhelpmember = new Discord.RichEmbed() // sets a embed box to the variable embedhelpmember
              .setTitle("**List of Commands**\n") // sets the title to List of Commands
              .addField(" - help", "Displays this message (Correct usage: *help)") // sets the first field to explain the command *help
              .addField(" - info", "Tells info about myself :grin:") // sets the field information about the command *info
              .addField(" - ping", "Tests your ping (Correct usage: *ping)") // sets the second field to explain the command *ping
              .addField(" - cookie", "Sends a cookie to the desired player! :cookie: (Correct usage: *cookie @username)") // sets the third field to explain the command *cookie
              .addField(" - 8ball", "Answers to all of your questions! (Correct usage: *8ball [question])") // sets the field to the 8ball command
              .setColor(0xFFA500) // sets the color of the embed box to orange
              .setFooter("You need help, do you?") // sets the footer to "You need help, do you?"
          var embedhelpadmin = new Discord.RichEmbed() // sets a embed box to the var embedhelpadmin
              .setTitle("**List of Admin Commands**\n") // sets the title
              .addField(" - say", "Makes the bot say whatever you want (Correct usage: *say [message])")
              .addField(" - mute", "Mutes a desired member with a reason (Coorect usage: *mute @username [reason])") // sets a field
              .addField(" - unmute", "Unmutes a muted player (Correct usage: *unmute @username)")
              .addField(" - kick", "Kicks a desired member with a reason (Correct usage: *kick @username [reason])") //sets a field
              .setColor(0xFF0000) // sets a color
              .setFooter("Ooo, an admin!") // sets the footer

  bot.login(BOT_TOKEN); // connects to the bot

  <p>It is the only file in my bot folder except the package.json, package-lock.json and all the node_modules.</p>
  
  <p>What I'm trying to do is type in discord *purge [number of messages I want to purge] and get the bot to delete the amount of the messages I asked it to delete, PLUS the command I entered (for example, if I ask the bot to delete 5 messages, he deletes 6 including the *purge 5 message.</p>
  
  <p>Any help would be much appreciated, thanks!</p>
