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.

Svelte 5: Runes
Putting the runic terminology aside and looking into how the signal primitive is implemented should dispel the magic. I learned a lot from examining preact's implementation: https://github.com/preactjs/signals/blob/main/packages/core/...

- Why are signals still not so popular?

Is redux ecosystem still active?
All the frameworks are starting to adapt them. You can easily add them to react project as well. https://preactjs.com/blog/introducing-signals/

DreamBerd; Perfect Programming Language
Signals are a design paradigm for reactive programming which have recently trended in the JS frontend space. For e.g., https://preactjs.com/blog/introducing-signals/

Which UI framework should I pick up as my first?
Compare Vue's reactivity system to the principles the Preact authors write about here:

Super Charging Fine-Grained Reactive Performance
Reactivity libraries are at the heart of modern web component frameworks like Solid, Qwik, Vue, and Svelte. And in some cases you can add fine-grained reactive state management to other libraries like Lit and React. Reactively comes with a decorator for adding reactive properties to any class, as well as prototype integration with Lit. Preact Signals comes with a prototype integration with React. Expect more integrations as these reactivity cores mature.

Empire (State) has gone 1.0!
State solution should not be a framework, this is what I dislike in riverpod as well.. its a FRAMEWORK... compare to the simple useSignal hook that preact has https://preactjs.com/blog/introducing-signals/ this looks like an overkill.

React VDOM vs Preact Signal Performance flame graph

For UIKit apps, what is best practice for VC listening for updates from a service?
I use RxSwift/RxCocoa and The Binder Architecture. That way View Controllers always show the most recent data from the service.

Xcode double segue
I do this with RxSwift and my CLE library. Using those you can do something like this:

Anyone have a clever way of using third party packages in Swift Playgrounds?
I've tried going to RxSwift's source and copying the RxSwift folder into my playground file's Source folder but no dice, it complains about a source file not being found. I tried flattening all the files into one folder and had the same problem.

DispatchGroup in Swift
We have defined what async code is, and two basic issues we could have when working with it: running tasks serially and in parallel. For running tasks in parallel we saw that DispatchGroup can be a simple solution for that. I will recommend using a library for this though. What I taught you here is basic async knowledge, but in real world scenarios, this won't be this straightforward, so using a battle tested library is always an advantage when working in production. I personally recommend using Apple's Combine if you can (it is supported in iOS 13 and above) or using RxSwift otherwise Finally, I can't finish this article without mentioning async-await. With async-await, probably all of this discussion will be a thing of the past. It lets us write async code that can be written like sync code. You can see the proposal (already implemented and that will be released in the next version of swift) here, and even try it in your code following a tutorial like this one.

RxSwift - easy, yet not obvious, tips
I think this is the most important thing to understand with all your heart. All subjects, relays and operators might seem scary, especially with Rx-hermetic jargon. But simplifying it in your head to a simple collection will help you to understand all concepts easily. For me it was a sudden click. If you want to learn more, official docs are great source and emphasize this concept: https://github.com/ReactiveX/RxSwift/blob/main/Documentation/GettingStarted.md#observables-aka-sequences
