possible answer invalidation by Hadwig on question by Hadwig: codereview.stackexchange.com/posts/217231/revisions
Your question is off-topic here for a couple of possible reasons. (1) it appears to be a code review style question. (2) If it is about faulty code, then you should be describing what you want to happen, what code you have, and what's going wrong with the a Minimal, Complete, and Verifiable example so that we can run the code ourselves. — Enigmativity 41 secs ago

I didn't cast any votes, but the close votes show that someone thinks your question is too broad. However, your question currently asks if there is "a better way" to do something that you have already accomplished. This sounds like you are either asking for code review, or seeking opinions - both of which are off-topic for SO. I suggest you try to reformulate your question so that it focuses on a much more specifc programming problem: what exactly do you think your current solution fails to achieve? — ekhumoro 47 secs ago

Does your code currently work? Can you make a working example? Are you asking how to make it "better"? If so, this question is off topic for StackOverflow and would be better suited for CodeReview as you are asking about refactoring working code and not about an error — Taplar 34 secs ago

@HIlle No - there's no reason why it's off-topic here. I'd say it falls under the first bullet point listed in the help "a specific programming problem". The fact that it might also be on-topic at code review doesn't mean it's off-topic here. — DavidW 14 secs ago
