How do you measure beauty? You can't: "beauty" is subjective. And even if you try e.g. count the times you use recursion vs. iteration: that metric is subjective and not grounded in reality.
Sometimes recursion does allow you to reason about code more easily or come to a working solution faster, sometimes it does not.
Measure the concrete: CPU time and memory consumed. Iteration will likely trump recursive methods w.r.t both these metrics. If it doesn't, you can likely transform your iterative algorithm to one that utilizes SIMD (not always).
- mbivert 2y ago> How do you measure beauty? You can't: "beauty" is subjective Let me try: in classical dance, martial arts, or even skateboarding, advanced skills manifest as effortlessness: the movements comes naturally, they're not forced, things just flow. If you compare a typical functional (recursive + pattern matching, but the point would stand even with a fold) factorial with an imperative one (for loop), the functional approach is more effortless, you have to be less explicit about what's going on. It's more eloquent. However as you seem to imply, when we're programming, the focus should be on delivering something that works as expected; this particular kind of aesthetic is secondary at best.
- o11c 2y agoOften I get the impression that beauty is defined as "how far is this from what the computer can actually do efficiently?"

- vsuperpower2020 2y agoI never understood anyone who used such strong language like "beauty" when talking about something mundane like recursion. I suspect it's just in-group language like how a cult understands the meaning of their own words, while to outsiders it would appear nonsensical. I have seen other groups appropriate the word "beauty" too, like people who chronically overeat.

- burnished 2y agoNope, it just has its own beauty. The material blew me away in school. What culty group even exists around recursion anyway? Can you get me an invitation?
- burnished 2y agoThis is a painfully stemlord response. 'Aesthetic qualities cannot be objectively measured therefor they do not exist'. Christ. Its fine to pick a metric to evaluate one thing against another, its another to deny that there are other ways to value things.
