title: Problem with client.channels.get();/client.channels.find();
body: <p>I have been working on a discord bot and I want to send a message as soon as it gets online in a set announcement channel. I think I know how to make it work but I keep getting the same problem. I've read several articles but they don't solve the problem I have <code>client.channels.get is not a function</code>.
  I don't just want to change it to a channel Id as I want it to be possible to be used on other servers than mine. I am a newbie in discord API and coding in general. That is why I don't use too advanced coding as I want to learn what it does instead of copying something I don't understand.
  Thanks.</p>
