I completely agree with your assertion about readability. The same code can be broken down and refactored in many ways to satisfy different requirements. In this article, my design goal was to come up with a way of expressing a hierarchical view of operations so that you first see the forest, then the trees. You do sacrifice the ease of debugging in this case, but that could be mitigated by inserting various tap functions into the composition that would serve as observation or debugging points.
Another tool that could help alleviate the problem of intermediate results and aid understaing is to leverage a type system like TypeScript, which provides annotations for well-typed functions. This allows you to observe the shape of objects by hovering over different parts of the composition. I was thinking of writing a follow-up article that would illustrate how that would cover the gap with this approach.
I wouldn't use this approach to teach clean code to a beginner, though, there's too much to unpack here. Simple imperative code, as in the first example, would have been the example I would have used, and there are more important principles to cover first.

Thank you, those are good points you raise. ☺️
