Doing every simple thing that used to be done in "normal procedural" way in functional paradigm instead when using something like Scala or fp-ts in TypeScript.
Causing engineers to completely change their mental model of how the code runs, which I still have intuitive trouble imagining correctly and I see it with other developers as well. A lot of energy goes into trying to understand how to do a simple action. It is much harder to read the code and have a correct mental model as well.
lol it's the opposite? map, flatmap, fold etc are very clearly defined operations with very clear use cases and rules. loops are not, you can do whatever you want (often mutating the underlying, rug pulling you every iteration)
not being familiar with fp doesn't mean it's objectively worse
It likely also depends on the person so I couldn't speak on behalf of everyone. I have been exposed to it to some extent, not the majority of work for over 5 years and it still intuitively is challenging for me. So similar task would take longer to code and existing code would take longer to understand. Significantly more effort would go to that.
I feel like I spend more time and energy on how to get something done functionally rather than focusing on what the correct business logic should be.
