Doesn’t declarative programming and by extension functional programming adhere more to the ethos of ‘Programming as Theory Building’ ? I recently started building mobile apps using Flutter after a decade of developing apps using imperative programming languages and I’m really in love with the declarative nature of flutter. Similarly for web development, I always loved HTML and so HTMX has been a boon for me. I’m using Go for backend, but I’ve been thinking whether I should move on to a proper functional programming language like Elixir with Phoenix since I’m liking declarative programming very much?
