Coq VS ReasonML

Are those more important than, say: - Proven with Coq, a formal proof management system: https://coq.inria.fr/ See in the real world: https://aws.amazon.com/security/provable-security/ And check out Computer-Aided Verification (CAV). - Source: Hacker News / 6 months ago

Dafny and Whiley are two examples with explicit verification support. Idris and other dependently typed languages should all be rich enough to express the required predicate but might not necessarily be able to accept a reasonable implementation as proof. Isabelle, Lean, Coq, and other theorem provers definitely can express the capability but aren't going to churn out much in the way of executable programs;... - Source: Hacker News / 10 months ago

Still, there are many useful tools based on these ideas, used by programmers and mathematicians alike. What you describe sounds rather like Datalog (e.g. Soufflé Datalog), where you supply some rules and an initial fact, and the system repeatedly expands out the set of facts until nothing new can be derived. (This has to be finite, if you want to get anywhere.) In Prolog (e.g. SWI Prolog) you also supply a set of... Source: 10 months ago

This type of thing can help you formally verify code. So, if your proof is correct, and your description of the (language/CPU) is correct, you can prove the code does what you think it does. Formal proof systems are still growing up, though, and they are still pretty hard to use. See Coq for an introduction: https://coq.inria.fr/. - Source: Hacker News / 12 months ago

Hey HN, at Ahrefs we have been working on an online book that hopefully helps React developers get up and running with Melange, an OCaml to JavaScript compiler. You can read more about Melange here: https://melange.re/. There are still a few chapters that we'd like to add before considering it "complete", but it might be already helpful for some folks out there, that's why we decided to publish it early. The book... - Source: Hacker News / 2 months ago

ReScript is "Fast, Simple, Fully Typed JavaScript from the Future". What that means is that ReScript has a lightning fast compiler, an easy to learn JS like syntax, strong static types, with amazing features like pattern matching and variant types. Until 2020 it was called "BuckleScript" and is closely related to ReasonML. - Source: dev.to / 4 months ago

- ReasonML - https://reasonml.github.io/ - essentially ocaml with nicer syntax. - Source: Hacker News / 4 months ago

This tracks with how I've seen "normal" languages converge on similar, flawed imitations of better type systems through tools and repurposed syntax. Thank you for confirming. Do you have any recommendations or warnings regarding general languages which reach in the opposite direction? Reason[1] and F#[2] are both examples: they attach pre-existing ecosystems and compile-for-$PLATFORM tools to OCaml-like typing.... - Source: Hacker News / 8 months ago

Why not use https://reasonml.github.io/ instead? Or just use Typescript? Source: 12 months ago
