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.

Anyone using the data types Map and Set IRL?
I recently scanned out codebase with https://github.com/sindresorhus/eslint-plugin-unicorn/blob/main/docs/rules/prefer-set-has.md and found many instances of potential "accidentally quadratic" uses of array.includes instead. gas a nice autofix to convert to set. there are some fun and sometimes useful lint rules out there...

this has broken my code 3 times
There’s an ESLint rule for that (albeit in a plugin)
-
Array.reduce() feels like a cheat code/superpower if you know how to use it.
Many popular eslint configs have even introduce rules to warn on its usage for these very reasons.
-
Why are functions declared inside a component instead of directly in the file.

TIL about the Nullish Coalescing Operator in Javascript (??)
I find eslint-plugin-unicorn package pretty useful for updating old code. With IE11 dead and NodeJS v12 LTS sunsetting soon, it's a brave new world.

Code Review chronicles: destructuring, linting and one valid reason for Typescript
Default parameters should not be passed to a function through an object literal. The foo = {a: false} parameter works fine if only used with one option. As soon as additional options are added, you risk replacing the whole foo = {a: false, b: true} object when passing only one option: {a: true}. For this reason, object destructuring should be used instead. Linter rule

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.
