| >aggressive You are reading aggression in based on the fact that I am disagreeing with you. It is text over the internet. Whatever tone you are gathering is purely imagined. I would suggest you visit fewer circle jerk areas and discuss things. People telling you you’re wrong and why is not aggression. >source I mean. I assume you’re a developer as you have a strong opinion on immutability. So just test it? It isn’t as if testing the impacts of immutability of performance is a difficult thing to test out. It is actually difficult to find results because functional programmers have flooded the internet with “yes performance is impacted, but performance doesn’t matter. Performance is a premature optimization” Nevertheless, even with things smaller than a register, performance is impacted here: https://product.hubspot.com/blog/immutability-and-performanc... By several X. Now get it objects that are larger than a register with numerous stack blowing deep copies and the effects are massively more pronounced. The fastest Haskell game engine looks like PlayStation 2 on modern hardware. I mean. That immutability massively hurts performance is not a point of contention, even among immutability fanboys. >did you hallucinate I think you forgot your own post. You stated that CoW is trivial and I gave you a specific reason as to why that claim is a lie. |
