Elixir

“I think Elixir's terseness, introspection capabilities, and strong ecosystem-wide quality guards really help.”

“Elixir is the best language, plus the BEAM, for everything that consumes from the network or listens on a socket.”

“It encourages a stricter functional style, that already makes for better code than what many people produce”

“An expressive and well designed language (elixir) is objectively better than a less well designed language like python.”

“The stable nature of the language, and the static/immutable nature of constructs, presumably really helps moving safely here.”

“with gradual typing now in elixir, I'm weighing whether or not gleam offers anything special enough to get me spending time there instead of just using elixir”

“This has never been an issue in Elixir, because instead of a comment, you'd just improve the pattern matching in the function definition.”

“I do not feel very confident about parts of it that don't have complete test coverage, due to the lack of static typing.”

“Elixir, I still had to know my whole call chain to know what I could do with my incoming parameters.”

“It is easy to write short, specific functions in Elixir and adding Typespecs to theses functions is like typing a block of code.”

“the Erlang platform gives you so many guarantees that even if you somehow make a mistake, it is never catastrophic”

“I spent 3 months analyzing failures caused by - what looked like - dirty builds but was caused by unstable compilation order.”

“even more interesting than gradual typing: when type annotations get implemented, Elixir will apparently be the first somewhat notable language that supports full set theoretic types”

“imho thinking about Elixir in types means you arent treating is like a lisp any more, which imho undermines how great Elixir is”

“I find the optional parentheses, and the way that keyword lists are defined to be the two biggest stumbling blocks”

“Elixir gives you too much freedom on how to write something on a syntax level which really annoyed me.”

“the design can push people into writing unnecessary matches/guards just to trigger the typechecker”

“I love everything about Elixir, but Elixir constantly makes me doubt myself like no other language.”

“Durable, 'enterprise grade' software patterns are baked into the runtime and into common, stable libraries that everyone uses”

“Structural pattern matching is the only feature I dearly miss, but that's a feature of the language”

“with coding agents it feels like the language isn't the best choice - slow compile time, weak type system”

“There’s just no true ownership and direction that can come close to that of Jose Valim and Chris McCord in the JS ecosystem.”

“it is remarkably robust, my impression is that you can more or less yank RAM modules out of the server while it is running”

“This is how you build rapidly and bypass all of the long term maintenance issues that we always have to fix”

“functional languages like Elixir are more naturally suited for running on systems with lots of CPUs and threads”

“All the Elixir constructs distinct from ruby are well applied: pipes, multiple function clauses, pattern matching, etc.”

“BEAM is great at surviving process crashes, but if the whole cluster goes down or you redeploy, that in-memory state evaporates.”

“the language itself is so easy to write business logic in that it takes half as long as it would in another language”

“I do wish things would go the other way—and have all the BI/ML/DS pipelines and workflows folks are building in Python and have them come to Elixir”

“having something functional, fault-tolerant, and concurrent underpinning work that's naturally highly concurrent and error-prone feels like a _much_ more natural fit”

“I've been writing Elixir in production since ~2018 and it continues to amaze me at the quality of code it produces.”

“the language server in my experience is very fickle and flat out doesn't work if you have an older Elixir project”

“I think elixir has some amazing ideas. I love pattern matching. However! Just like all other interpreted languages”

“multiple inheritance fits the same category and with minimal squinting same features can be found in languages such as Clojure or Elixir”

“Sure Elixir is fine to work with, the thing is in the back of my mind I'm thinking it's way more likely to end up embedding Python libraries in Elixir code”

“The GenServer crashes and is immediately restarted, with a clean slate, with the correct peer-services in the correct state.”

“As someone who built an entire startup in elixir, its a good time to bring up that elixir has an excellent interop with rust”

“allows you to get the kinds of fall over, scaling, and robustness of k8s at a much more responsive and granular level”

“I love flattening hierarchy and dealing with edge cases right in function definitions using pattern matching.”

“Indestructible, simple, and everything is easy once you wrap your head around the functional programming.”
