//Scan 2 eggs and 3 magazines
cashRegister,scan ("eggs")
cashRegister.scan ("eggs")
cashRegister.scan ("magazine")
cashRegister.scan ("magazine")
cashRegister.scan ("magazine")

//Show the total bill
console.log('Your bill is '+cashRegister.total);

ReferenceError: scan is not defined

Have you scanned eggs twice and magazine three times?

What's wrong here?
