return-optics VS solid-docs

Yeah? I wrote something to deal with it too (https://github.com/toastal/return-optics) 5.5 years ago. You arguably chose the wrong data as `(model, Cmd msg, Maybe extMsg)` instead of `(model, Cmd msg, List extMsg)` which would give you more flexibility and still functions as a monoid on [] instead of Nothing, but allows multiple messages shrug. I tried this approach more recently and it involved me having to encode all of actions in a massive tree and then I still had issues with certain messages including now having to UUID all elements that that previously I didn't need to think about. It was a mess, but the best I could do with the tools at hand.

If you compare this to Halogen (https://github.com/purescript-halogen/purescript-halogen/blo...) where you still have purity but can set up subscribers and listeners from any component. It's much easier to use and for some components like dialogs, it's much simpler. And this actually isn't the best example because with the latest Halogen, Portals (https://github.com/purescript-halogen/purescript-halogen/pul...) was introduced so you can launch a dialog on the spot instead of even needing to communicate between them at all.

React has introduced measures like batching state updates, background concurrent rendering and memoization to tackle this. My opinion is that the best way to solve the problem is by improving their reactivity model. The app needs to be able to track the code that should be re-run on updating a given state variable and specifically update the UI corresponding to this update. Tools like solid.js and svelte work in this manner. It also eliminates the need for a virtual DOM and diffing.

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

Solid.js is a very performant web framework that shares some similarities with React. For example, both use JSX, utilizing the function-based approach to components, but instead of using Virtual DOM, it converts your code to vanilla JS. Still, it is more famous for its approach to fine-grained reactivity by utilizing signals, memos, and effects. Still, the signal is the simplest and most known primitive of Solid. They contain value along with their getter and setter functions, allowing the framework to observe and update the changes as needed in the exact location in the DOM, unlike React, which re-renders the whole component.

Two well-known JavaScript frameworks and libraries used for creating user interfaces are React.js and Solid.js. Solid.js, a lightweight reactive library, prioritizes fine-grained reactivity and efficient rendering through a reactive programming model. However, React.js, which was developed by Facebook, is well known for its declarative architecture based on components and its handling of the virtual DOM (Document Object Model). Different approaches to state management and reactivity set these tools apart, even though they both enable developers to create dynamic and interactive web apps.

Solid.js like Svelte is quite new when compared to React, Angular, and Vue however it might be that pocket Hercules we've all been ignoring because we are so addicted to other frameworks. Solid.js is an interesting framework that deserves to be a part of this discussion. Solid.js pioneered the concept of signals when other Javascript frameworks made reactivity and state management a nightmare for developers, a factor that has contributed to the growth of Solid. Solid.js is incredibly easy to adopt and it aims for a simpler syntax and learning curve compared to other frameworks. It emphasizes the use of pure Javascript functions and avoids concepts like hooks.

React Server Components are the poster child for that trend, but other frameworks such as Solid or Qwik rethink client-server interactions from the ground up.

If you aren't married to the react paradigm, I had a great time with solid.
