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.

You Don't Need React
ts-pattern has been a decent band-aid for the lack of native pattern matching, but obviously has downsides that could be avoided if it was built into the language.

TypeScript Is Surprisingly OK for Compilers
With how powerful the type system is you can implement pattern matching via a library pretty convincingly, https://github.com/gvergnaud/ts-pattern is definitely the go-to. That being said pattern matching is hardly a requirement for being ok for implementing compilers.
-
[AskJS] C# in every Node.js job posting?
There's a proposal to add something like that to JavaScript but it's been stuck in limbo since 2017 although there are libraries like ts-pattern which implement it already.
- Rust Appreciation Thread
-
Safer Type Checking At Both Runtime and Compile Time
Otherwise, go for a pattern matching implementation like ts-pattern (which has exhaustiveness checking and has a builder pattern API) or ex-patterns (which im not sure if it has exhaustiveness checking, but it's a little more capable and is inspired by pattern matching in elixir, and has an argument order based API)
-
Safer exhaustive switch statements in TypeScript
Here is a library providing the described logic with a nice interface. I've used it before and others seems to find it helpful too.

libraries you are happy that you discovered them
I've use used ts-pattern before to simplify some complex if/elses
ts-pattern: https://github.com/gvergnaud/ts-pattern (pattern matching)
-
Write fewer tests by creating better TypeScript types
Switch statements are extremely limited and suffer from a fall-through hazard that can lead to errors and bad practices. Thankfully, several npm packages can help with type-narrowing discriminated unions, and the ts-pattern library is an excellent choice.

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.

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