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.

Ask HN: Hey Functional Programmers, how did you learn functional programming
fp-ts is hard to learn. Its docs, whilst improving, aren't great and it's applying pure functional concepts to a language which isn't designed for it. The outcome is surprisingly good but it's hard to understand as a newcomer why certain design decisions have been made, or what patterns are and are not idiomatic.
I'd recommend learning Haskell in your free time. It's a major paradigm shift but once it clicks you'll find it a lot easier to translate those concepts into fp-ts.
I went through this journey a couple of years ago, and now write heavy fp-ts code full-time - including maintaining fp-ts-std[1] - as well as some paid Haskell gigs on the side. Do feel free to reach out if you want any guidance at all, you'll find my email on my personal site[2]. The FP Slack is also a great place to ask for help with anything FP, including fp-ts - if you send me an email I can have an invitation sent to you.

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.
