Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Tired of Typescript? Check out ReScript!
ReScript is a fully typed language with an easy to understand JS like syntax, blazing fast compiler, that compiles to JavaScript. You can easily drop it into an existing project, and there is even a way to generate TypeScript types if you want to add it to a TypeScript project!

Learning Elm by porting a medium-sized web front end from React (2019)
If you’re a front-end developer, you should checkout ReScript[1], supposedly a JS-oriented successor of ReasonML and developed by the ReasonML team.

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.

Ask HN: Interest in a Rust-Inspired Language Compiling to JavaScript?
As another commenter has already suggested, ReasonML has a lot of what you described here.
However, modern JS-oriented toolchain for ReasonML is called ReScript and you can learn more here: https://rescript-lang.org/

How does one write React apps in a purely functional style without making the entire codebase a mess?
ReScript (before BuckleScript) https://rescript-lang.org/ is a functional language that can also use OOP. Ideal for Javascript and Typescript projects, React and servers. It integrates perfectly with Javascript and Typescript code https://rescript-lang.org/docs/react/latest/introduction

Show HN: EdgeDB Cloud and 4.0 with FTS and Auth
Thank you!
We invited Gabriel because we think what he's building is pretty cool. It showcases so much about EdgeDB: its type system, data model, query language, composability, introspection, etc.
I'm not a ReScript user myself. What I know is that it's a functional programming language somewhat heavily inspired by OCaml. Their website goes into details [1]

Strong typing, a hill I'm willing to die on
You might want to look into ReScript (https://rescript-lang.org/). It has strong static typing with type inference, and it is very fast.

Building React Components Using Unions in TypeScript
This is because a “Tagged Union”, another word for TypeScript’s Discriminated Union, is a way to “tag which one is in use right now… we check the tag to see”. Just like when you’re shopping and check the tag of a piece of clothing to see what the price is, what size it is, or what material it’s made out of. Languages like ReScript compile many of their Unions (called Variants) to JavaScript Objects that have a tag property.

Converting a JavaScript React app to a ReScript React app.
ReScript is "Fast, Simple, Fully Typed JavaScript from the Future". Let's take a look at how we can add it to an existing React project.

OCaml 5.0 Alpha Release
For nested parallel computations (think Scientific Programming, where one would use OpenMP, Rust Rayon, etc), we have domainslib [1]. Eio, a direct-style, effect-based IO library is pretty competitive against Rust Tokio [2]. The performance will only get better as we get closer to the 5.0 release.

PR to Merge Multicore OCaml
1. Domains are the unit of parallelism. A domain is essentially an OS thread with a bunch of extra runtime book-keeping data. You can use Domain.spawn (https://github.com/ocaml-multicore/ocaml-multicore/blob/5.00...) to spawn off a new domain which will run the supplied function and terminate when it finishes. This is heavyweight though, domains are expected to be long-running.
2. Domainslib is the library developed alongside multicore to aid users in exploiting parallelism. It supports nested parallelism and is pretty highly optimised (https://github.com/ocaml-multicore/domainslib/pull/29 for some graphs/numbers). The domainslib repo has some good examples: https://github.com/ocaml-multicore/domainslib/tree/master/te...
3. We've not tested against other forms of parallelism. There isn't anything stopping you exploiting SIMD in addition to parallelism from domains.
4. No, we've not compared performance by OS.
5. No plans for the multicore team to look at accelerator integration at the moment.
