Why would I not be familiar with the language of the code base I'm working with? This is a fallacy.

Secondly, I don't use Ruby, and from what I can tell, it's finding if any two non-equal elements in a given array sum up to a given number n.

I worked on several golang projects. It gets tedious and messy very quickly seeing code bases littered with one-use functions with what basically amount to map/filter calls being expanded into multiple line for loops. Not to mention it makes exploratory debugging much more tedious.
