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/...

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/

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.

Simulate global state tradeoffs in React concurrent mode
If you aren't sure why state tearing was a hot topic a few years ago, when React's concurrent mode was first discussed, this github discussion should help: https://github.com/reactwg/react-18/discussions/69.
Tanner Linsley had a great post on twitter that suggested that concurrent rendering was fundamentally at odds with fine-grained reactivity, so to better understand what he was talking about I decided to write this demo.

useAsyncState in react, no more unnecessary useEffects.
But it does since React 18.

ELI5, why is ReactDOM.createRoot an improvement over ReactDOM.render?
From the React WG:
- I know my component is re-rendering because a console.log I put in the component is logging in the console. However when I use the inspector to see why it re-rendered, its saying that it didnt re-render. How is this possible?
