You can .send() from JavaScript and .receive() from Ruby. But if you use "action" as a field in the hash, it treats it as a named action and receive() doesn't work.
Reloading. In general, reloading is a weird process. Reloading the browser can sometimes but not always reload the Ruby classes. Channel objects don't seem to reliably reload on the Ruby side, just in general.
In the documentation, streams vs channels. How they're named, how they're used.
Multiple ActionCable servers. Which is why "disconnect" operates by sending a pub/sub message to all servers to disconnect everybody "identified_by" what you sent.
Identified_by. Never really explained. Seems to only be usable for .disconnect?
