Connect bot to new channel via function?

Chat and IRC
3

I don’t use twitch.js, but it seems you have to do :

chat.join(channel1).then(channelState => { }) 
chat.join(channel2).then(channelState => { }) 
chat.join(channel3).then(channelState => { })

With pureJS and Websocket (=> Like the chatbot.js example) you have to do :

webIRC.prototype.onOpen = function onOpen() {
    const socket = this.webSocket;
    if (socket !== null && socket.readyState === 1) {
        socket.send('CAP REQ :twitch.tv/tags twitch.tv/commands twitch.tv/membership');

        socket.send('PASS ' + this.password);
        socket.send('NICK ' + this.username);
        socket.send('JOIN ' + this.channel);
