Flow Type VS ReasonML

I love JS, but I want types. I don't want TypeScript though, but I'll do it if the job requires it. Has anyone tried building in flow for a large project? This was facebook's static type checking approach: https://flow.org/. - Source: Hacker News / over 1 year ago

In my examples, I’ll use the Flow type system so that it’s easier to follow the idea. The code consists of two parts: a service API and a recommendation flow. - Source: dev.to / over 1 year ago

You think we could try to make it such that people use JS + Flow the static type checker. Source: over 1 year ago

The two biggest contenders in adding static types to JavaScript are Flow (by Facebook) and TypeScript (by Microsoft). As of date, there is no clear winner in the battle. For now, we have made the choice of using Flow. We find that Flow has a lower learning curve as compared to TypeScript and it requires relatively less effort to migrate an existing code base to Flow. Being built by Facebook, Flow has better... - Source: dev.to / over 1 year ago

Just FYI, Facebook has a JS dialect called Flow. There was a point in time that Flow and TypeScript were duking it out, but clearly TS has won. I think Flow is still used inside Facebook, but I don't think it has really caught on in the larger developer ecosystem. Source: over 1 year 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
