Thank you! I was actually about to write something similar.
I often see people that use nodejs for payment stuff. Even here on dev.to there was an interview with a guy who said that they factored out a payment system and wrote it with nodejs and mongodb! That's like asking someone: "What are two worst tools for building a Payment system?"
Why? Because Javascript has only floating point numbers and payment data is inherently relational.
Really gets me angry
