Question

If anybody here has dug into the source code of

the guard bot, i'm trying to understand something here. This is a little snippet from routingFn.js
const [ , command, username ] =
/^\/(?:start )?(\w+)(@\w+)?/.exec(message.text);
username is always undefined even when the message content is /somecommand @foobar
even when /warn and /unwarn is used, so i was wondering whats the purpose of defining username, and how else it was working
