title: Get random Discord user
body: <p>Im creating a bot that taggs a random user, but im having some difficulties.</p>
  
  <p>How can I get a random user? Im currently doing this:</p>
  
  <pre><code>let usersCount = message.guild.memberCount;
      let users = Array.from(message.guild.members);
      let randomNumber = Math.floor(Math.random() * usersCount);
      let randomUser = users[randomNumber];
  
      console.log(randomUser);
  </code></pre>
  
  <p>But its returning this, with the whole guild:</p>
