ReasonML Reviews and Details

Is ReasonML good?

Social recommendations and mentions

• Gleam is my new obsession

  Reason (https://reasonml.github.io/) is the JS like syntax for OCaml. - Source: Hacker News / 10 months ago

• A 10x Faster TypeScript

  OCaml and Haskell already have that nice type system (and even more nice). If OCaml's syntax bothers you, there is Reason [1] which is a different frontend to the same compiler suite. Also in this space is Gleam [2] which targets Erlang / OTP, if high concurrency and fault tolerance is your cup of tea.

• Ask HN: What less-popular systems programming language are you using?

  > The syntax is also not very friendly IMO. Very true. There's an alternate syntax for OCaml called "ReasonML" that looks much more, uh, reasonable: https://reasonml.github.io/. - Source: Hacker News / over 1 year ago

• An Ode to TypeScript Enums

  When I see this it makes me want to run for ReasonML/ReScript/Elm/PureScript. Sum types (without payloads on the instances they are effectively enums) should not require a evening filling ceremonial dance event to define. https://reasonml.github.io/ https://rescript-lang.org/ https://elm-lang.org/ https://www.purescript.org/ (any I forgot?) It's nice that TS is a strict super set of JS... But that's about the only... - Source: Hacker News / over 1 year ago

• How Jane Street accidentally built a better build system for OCaml

  Https://ocaml.org/docs/toplevel-introduction#loading-libraries-in-utop https://reasonml.github.io/ looks cool, OCaml with javascript. - Source: Hacker News / over 1 year ago

• OCaml Syntax Sucks

  Fortunately, the OCaml compiler is very modular, and there have been efforts to make things more... reasonable. - Reason, a different syntactic frontend for regular OCaml: https://reasonml.github.io/ - ReScript, a language with OCaml semantics that compiles into: JS https://rescript-lang.org/ (I suppose it's a reincarnation of js-of-ocaml). - Source: Hacker News / over 1 year ago

• Comparing OCaml and Standard ML (2020)

  OCaml makes so much sense to me -- it's just a shame that the syntax has some weird decisions. I wish ReasonML (https://reasonml.github.io/) would come back -- it's a new syntax for the same language, kind of an Elixir/Erlang thing. - Source: Hacker News / about 2 years ago

• ReScript has come a long way, maybe it's time to switch from TypeScript?

  Ocaml is still a wonderful language if you want to look into it, and Reason is still going strong as an alternate syntax for OCaml. With either OCaml or Reason you can compile to native code, or use the continuation of BuckleScript now called Melange. - Source: dev.to / about 2 years ago

• Melange for React devs book, alpha release

  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 / over 2 years ago

• ReScript: Rust like features for JavaScript

  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 / over 2 years ago

• Ask HN: Interest in a Rust-Inspired Language Compiling to JavaScript?

  - ReasonML - https://reasonml.github.io/ - essentially ocaml with nicer syntax. - Source: Hacker News / over 2 years ago

• Earning the privilege to work on unoriginal problems

  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 / almost 3 years ago

• VN Compiler. Why using Fable is too difficult. (Pt. 1)

  Why not use https://reasonml.github.io/ instead? Or just use Typescript? Source: about 3 years ago

• My Thoughts on OCaml

  ReasonML and ReScript are a (more or less the same) new syntax on top of OCaml. ReScript only targets JS, while ReasonML targets both JS and the native archs OCaml supports. Facebook and Bloomberg are using ReScript internally, afaik. Messenger.com is written in it. Facebook also maintains React bindings to ReScript. https://rescript-lang.org/ https://reasonml.github.io/. - Source: Hacker News / about 3 years ago

• why

  There is also reasonml for Web development. Source: over 3 years ago

• Haskell is the one of the most hardest code

  OCaml is probably the closest in performance, but the language is so idiosyncratic they had to invent a wrapper around the entire language https://reasonml.github.io/. Source: over 3 years ago

• ReScript 10.0

  IT's a META project based/fork of ReasonML (https://reasonml.github.io/). They are ocalm dialects thats compile to Javascript. Advantage vs Typescript is a strict type system. - Source: Hacker News / almost 4 years ago

• Ask HN: Learning Functional Programming in 2022?

  Sounds like you are mostly frontend. I can highly recommend ReScript https://rescript-lang.org/ I learned a lot about functional programming from it. It is a more frontend focussed https://reasonml.github.io/ which is all based on OCaml. It has the same awesome type system and all the FP goodies while providing easy TS/JS interop and convenient escape hatches. It compiles (very fast) to highly efficient readable... - Source: Hacker News / almost 4 years ago

• A language which is basically "Haskell with C-Style syntax"?

  Reason may be the nearest thing to what you are asking for: It is essentially OCaml, but it trades the traditional ML syntax for a JavaScript-inspired (aka C-like) syntax. Source: almost 4 years ago

• functional programming and choosing the best fitting frontend framework (Vue 3 vs React)

  Reason ML comes from folk in facebook who work with react too. It's mostly inspired by functional programming language OCaml. So you can actually do it properly. And let everyone else keep their opinions to themselves. Including your own objections. Source: about 4 years ago

• Editor Support for ReasonML in VSCode with Melange

  I have been trying for a long while now to work with ReasonML files in VSCode and get some syntax highlighting. This has been a problem since ReasonML on the frontend has moved on to Rescript. The solution would be using Melange but I could not get the editor highlighting to work. I have a bunch of old ReasonML projects that I still refer to so losing the editor support has been less than ideal. The code still... - Source: dev.to / about 4 years ago
