Processing financial transactions is not the kind of software you want to make mistakes in. If something is supposed to happen, it is definitely supposed to happen. Not partially happen. Not maybe happen.

Thus, a company like Charles Rs uses a vendor-supplied accounting package. That vendor has a professional services team, so when the behavior needs to be customized, Charless company outsources that development to the vendor.

Of course, years later, that code needs to get audited, and its about then that you find out that the vendor outsourced their professional services to the lowest bidder, creating a less-than-professional service result.

If you want to make sure than when the country code is equal to "HND", you want to be really sure.

if(transaction.country == config.country_code.HND || transaction.country == config.country_code.HND)
    parts[0] = parts[0].replace(/\B(?=(\d{3})+(?!\d))/g, ",");
else
    parts[0] = parts[0].replace(/\B(?=(\d{3})+(?!\d))/g, ".");
