Discussion on: 3 clean code principles for the functional programming beginner

Using global variables is a smell and common source of bugs, especially in a language like javascript. I'd recommend to read the book Clean Code. It has code examples in Java but the principles are language agnostic.

I see what he's getting at.

I don't like how he explained it.

The idea that the doggos variable shouldn't be duplicated is pretty self-evident, as it's both constant and effectively an additional helper function.

I doubt it belongs in the global scope, but it's reasonable to put it into the same scope as the functions that use it.

You are right it is a constant, I just wanted to highlight the duplication part from a beginners perspective
