Both on the job (where I’ve always conceded to team preference for imperative loops) and observing the community (hating on reduce is a whole meme on JavaScript/TypeScript Twitter, and the contrary meme has never shown up at least on my feed). And I honestly understand why it’s not very popular. Reduce/fold is a very FP concept which isn’t particularly idiomatic in real world JS. When I learned and embraced it (myself coming from a JS background), it took dozens of real uses before I felt like I had committed to my own memory what’s actually happening. And by then I think I was writing Clojure.
