title: Discord.JS - How do i see if message.content is in an array?
body: <p>So i am creating a Discord user verification bot that generates a 2048 bit key when you join a server, it will be used for verification if your account gets hacked or stolen so you can know the new account is the previous person.</p>
  
  <p>I have got the Key Generation down but i am having a problem with seeing if <code>message.content</code> is in some array</p>
  
  <pre><code>client.on("message", (message) =&gt; {
  var array = fs.readFileSync('./keys.txt').toString().split("\n");
  })
  </code></pre>
  
  <p>I am converting a text file to an array, but then i am stumped.
  The bot is suppose to check all messages for the key, if found it will tell all users that the new user is verified to be the old user in a channel.
  Can someone please tell me how to check if a message comes from an array? Thanks.</p>
