title: discord.js rateLimitPerUser is not a function
body: <p>I'm making a normal discord bot and I wanna set the slowmode here's my <strong>full</strong> code:</p>
  
  <pre><code>bot.on("message", message =&gt; {
  
  if(message.content.toLowerCase().startsWith(prefix+"slowmode")) {
    var str = message.content.split(prefix+"slowmode ");
    var num = parseInt(str[1],10);
    message.channel.rateLimitPerUser == rts;
    message.channel.send("Slowmode Setted");
  }
  </code></pre>
  
  <p>});</p>
  
  <p>but I get a error : </p>
  
  <pre><code>TypeError: message.channel.rateLimitPerUser is not a function
  </code></pre>
  
  <p>I also tried other ways like : </p>
  
  <pre><code>message.channel.rateLimitPerUser = num;
  </code></pre>
  
  <p>but they didn't work too. I searched the documentary and internet to set the slowmode but they didn't work too. [ sorry form my bad english :( ]</p>
