I was thinking that the other day and I think it's less Hashnode's fault as it is the community in general. It looks like a lot of the interest from the community is geared towards JavaScript with minor outliers here and there.
My native languages are C# and JavaScript and I think I've mentioned C# once and only then in reference to ArangoDB.
Paul is absolutely correct though, a surprising amount of the theory applied here can be applied elsewhere and if ypu have questions about another language, I'm willing to bet that there are those here that would be more than willing to help.
