title: client.startTyping is not a function (Discord.JS)
body: <p>I am trying to create a Discord bot using NodeJS and DiscordJS. However, when I try to use the <code>client.startTyping()</code> function, referring to <a href="https://github.com/hydrabolt/discord.js/issues/440" rel="nofollow noreferrer">https://github.com/hydrabolt/discord.js/issues/440</a> and <a href="http://discordjs.readthedocs.io/en/latest/docs_client.html" rel="nofollow noreferrer">http://discordjs.readthedocs.io/en/latest/docs_client.html</a>, it seems to return an error saying the function does not exist. How can I fix this?</p>

  <pre><code>client.startTyping(message.channel);
  for (i = 0; i &lt; (times + 1); i++) {
      message.channel.sendMessage(msg);
  }
  client.stopTyping(message.channel);
  </code></pre>
  
  <p>This is the error:</p>
