Compiler Development: Rust or OCaml?
As someone who wrote a fair amount of Rust and OCaml code, I have to agree with the author.
While working at Routine (YC W21), I was tasked with porting our core library to iOS to minimize code duplication. This was a lucky opportunity to write something resembling a compiler: it took in schemas described with our in-house data exchange library and generated C (for FFI) and Swift code (for the end-users, i.e., iOS developers).
Since Routine uses OCaml for everything (which was a big motivator for joining the company—I wanted to see how that would work out), I wrote it in OCaml. The end result is a 3-5k LOC project. It's by no means a full compiler, but it was lots of fun to write. The language got in the way incredibly rarely. On average, it made my life a lot easier.
We did encounter our fair share of issues, mostly due to the cross-compilation tooling (we initially used esy [1], flirted with Nix, and eventually switched to opam-cross-ios [2]), third-party libraries, and intricacies of FFI. Those do take their toll on sanity.

OCaml 5.0 release (including multicore and effects)
What's the current status of Esy? https://github.com/esy/esy
Any plans to backport its design back to Opam?

2021 at OCamlPro
It's great to hear that Opam is making progress! I just wished that it would be more deeply integrated with Dune. A package manager that doesn't build is not very useful to be honest. Currently the only way to not have to care about switches and be able to clearly specify dependencies is to use the esy package manager[1] (which had lock files a while ago).

PR to Merge Multicore OCaml
If you start a project today I would really try to use esy (https://esy.sh/)
I actually don’t use it myself but it seems to bring the modern programming language experience to OCaml

Another alternative is to use esy but I'm clearly biased here....

Frustrated by lacking cross platform support (hoping to be wrong)
Alternatively, you can use esy.sh for a simpler setup/build process (it does not require running in a Cygwin shell).

Opam, PNPM, Node, Esy, Docker, ReactNative on 128GB Mac
Running esy does not work. Apparently, my environment does not know that it is there. Anyone know what is going on here? I have posted this in the discussion for esy@next here. I will get back to you all when I figure this out.

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.

Ultimately, Dhall wasn’t verbose enough nor was I Dhall ninja, but something like TypeScript or ReScript probably would have been better.
