Ah, I tried offset, but didn’t know how it worked. That solved that issue, thanks a lot for that! 
It’s not a chat bot. I’m very new to node.js and programming in general so I’m trying to console.log all messages on a lot of channels. I don’t think it’s against ToS because of Chatterino basically doing the same.
I heard about data limits and whatnot, so I think I need to delay how fast I join the channels, but have no idea how.
