How that code example a style violation? I am not even sure how it's bad code. In JavaScript that would just return a value without the first index. What code style rule would solve for that in a meaningful way that you are willing to enforce uniformly on all concerns?
It is because if a file is made of a hundred 1-line functions that’s not good code. The separation of concerns is likely not meaningful and it’s detrimental to the reading/understanding of the file.
Why create a function that shortens/clarifies nothing and is used once? If you want to explain some code, use a comment, don’t make spaghetti
I’ve found all kind of bugs just refactoring code because poor code obfuscates them.
Your way of building things will lead to debt and bug reports
