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.

John Carmack on Functional Programming in C++ (2018)
Do it! Do it! Do it! If only for a couple of tests to see how much it changes the results. ;-)
Unboxing sums is a nice optimization but then you can't naively use switch-patern matching to deconstruct them.
I have a bunch of other things in Sasa and other libraries you might find useful. I'm not actively working on most of them anymore except for bug fixes. I learned a lot but didn't end up using a lot of these features as much as I'd hoped.
For instance, being able to create open instance delegates in a way that automatically works around the CLR limits against such delegates to virtual methods. Some of the concurrency primitives are also interesting, as they implement an efficient atomic read/write protocols for arbitrary sized types using only volatile reads/writes (ie. avoid torn reads), and a sort of LLSC using only volatile read/write and a single interlocked inc/dec. Also, I added a kind system to CLR reflection to make working with it much easier [2].
It seems we're thinking along the same lines for numeric types. I reproduced the Haskell numeric hierarchy [1], but I put that on hold because I was thinking a [Deriving] attribute would eliminate a lot of redundancy.
Just FYI, clicking Num on the main GitHub markdown page doesn't jump to the link on the markup.
Lots more to see if you're interested! I've played with parser combinators but never liked how they turned out, and settled on a simpler approach that was pretty interesting.

From a Lorry Driver to Ruby on Rails Developer at 38
I think it’s great that functional programming is making its way into traditional imperative languages - even JavaScript (I recently came across https://gcanti.github.io/fp-ts/ as a pretty extreme example)
Elixir/Erlang has function-level pattern matching, which I really like. I’ve yet to see it anywhere else, though my understanding is it came from Prolog.

Type-Safe Printf() in TypeScript
While I certainly agree, I've found that this is often an indication of too-complex an architecture, and a fundamental re-think being necessary. I've had projects that depend on [fp-ts], which end up incredibly generic-heavy, but still make it entirely through a typecheck(not build- typescript's just worse at that than other tools like esbuild) in seconds-at-worse.
Obviously depends on your organization/project/application, but I do like these things as complexity-smells.

Introducing fp-utils a functional utility library for Deno / Node
Unlike more comprehensive functional libraries like fp-ts, each module can be imported and resolved separately. If you just need options, simply add the option module and you're good to go.

Blog post: graphs and monads with Typescript
While it's quite abstract, I believe it may be useful to those of you who is interested to learn more about functional programming [in Typescript] and also get more intuition on diverse programming ideas. I use fp-ts as a functional programming library there.

Functional Programming Library for Golang by IBM
The library for TypeScript that this is influenced by is here:
https://github.com/gcanti/fp-ts
Interesting how both languages with this library converge to a similar syntax, due to heavy use of functions.

Is Scala worth learning in 2023?
Learn something that pays the bill first - nowadays it's Golang/Rust react/typescript. Then you can try some pure fp libs like fp-ts and fp-core.rs, and look through existing scala cats docs. If you'll feel bad about it - that's totally fine and expectable, fp takes a paradigm shift and not that many dev able to shift their brains way of thought due to basic psychological rigidity) (inability to change habits and to modify concepts/attitudes once developed). And that's purely a staffing and management issue - folks hired randoms out of the blue, and called 'em a team.

Application Bootstrapping with fp-ts
fp-ts, a library that caters to functional programming in TypeScript, comes with some micro-abstractions that already solve a few of our needs.

What are some strategies for ensuring correctness and fewer errors in dynamically typed languages?
Also, don't underestimate how powerful TypeScript can be in capable hands (namely Giulio Canti's). Check out fp-ts, for instance.

Use Pure Functions to understand functional programming
You are able to type it using function overloads, an example can be found here - link, line 236.
