The "vertical" example looks contrived in JavaScript, but if that's your thing, I think it's OK.

But please don't promote antipatterns from languages that actually have a pipe operator (like Elixir) such as the '''concat("!")''' where the previous implementation's version using an operator is much clearer and more idiomatic.

I see a ton of Elixir code where people shoe-horn things into a vertical pipeline where the "normal" code would be a lot more readable, for example invoking '''Kernel.+(2)''' instead of just doing '''my_var + 2'''
