How to execute a .bat file with a command (with a cooldown by user if possible) on the twitch chat

That’s cool, but when I try to open the JavaScript in cmd with “node bot.js” it gives me this error:

username: lyricalstring_lightsbot,
          ^

ReferenceError: lyricalstring_lightsbot is not defined

Could you help me?
