this.mission = 'secret'

— I have another question im sitting on it since yesterday and the whole day today and i dont know why js behaves that way:

Im working on a telegram bot. Everything is working fine but the file is getting large. Because of that i want to split the bot into diffrent java files one for admin one for 8ball etc.

Now to inizialize the bot i use that:

let myCoolBot = new TelegramBot(botToken, {polling:true});

when i export the variable myCoolBot and use it in my other file like this

eightBallBot = myCoolBot;

i get TypeError: Cannot read property 'onText' of undefined


When i look into the debugger i see that let myCoolBot = new TelegramBot(botToken, {polling:true}); is undefined.

How can i define it to something that isnt undefined or null ?
