title: Discord JS, reply to certain user ID
body: <p>I want to make a command where the bot will only reply to a certain user id. But I'm confused how to make it so (FYI I'm new on JS)</p>
  
  <pre><code>const userID = '&lt;@4608164XXX93150209&gt;'
  
  bot.on("message", function(message){
  if(!message.author === userID)
  {
  
  if(message.content === 'psst')
      {
          message.channel.send('Hello there!');
      }
  }});
  </code></pre>
