Note that that FAQ is from the "Legacy" docs site, and was written right after hooks were announced in 2018. The current docs site at https://react.dev teaches only hooks + function components as the standard approach.

For the initial rollout, we'll be trying to onboard a couple teams at a time so that we can make sure everything's working fine. Then we can start ramping up and opening usage more broadly.

That page is very out of date. They did later adopt a build step and switch to using JSX in much of the FF DevTools codebase. As an example, here's the Editor main component (same "latest" commit you pointed to): https:&#x2F

Hmm. I'm a bit surprised to hear you say that writing reducers "by hand" is simpler than with RTK. Per the docs examples (like https://redux.js.org/usage/migrating-to-modern-redux#reducer... ), hand-writ

Hi, I'm a Redux maintainer and creator of Redux Toolkit. Can you clarify what your concerns are with RTK? We specifically created it to simplify standard Redux usage patterns and eliminate common mistakes and bugs (like accidental muta

FWIW, the Firefox devs who were doing the WebReplay time travel debugging POC weren't, as far as I know, fired. Instead, they left and started Replay ( https://replay.io ), a true time-traveling debugger for JavaScript. I j

Hi, I maintain Redux and wrote most of our docs (including our current tutorials). Can you give some details on which parts of our docs you feel are "incomprehensible"? I'm curious which specific pages you've been looki

Hi, I maintain Redux and created RTK. I'm going to do my best @davidkpiano impression and point out that "Redux, as typically used, is _half_ a state machine" [0] , in that a typical reducer responds to actions regardless of

To clarify: based on conversations with Sunil and what he's posted publicly, Partykit's infra is a layer on top of Cloudflare Durable Objects. `y-partykit` is an integration with Yjs on top of that core functionality.

Yep, we actually have an RTK Query + Svelte sandbox in our examples page! https://redux-toolkit.js.org/rtk-query/usage/examples#svelte We've also seen people use RTKQ with Vue and NgRx as well, like this: -

Andrew Clark just moved over to Vercel. I believe they also got Dominic Gannaway, who used to work on the React team, although he said he'll be working on Svelte compiler stuff now.

I'd recommend https://www.internetingishard.com/html-and-css/ as a good initial overview of HTML and CSS concepts. Also, I wrote a "How Web Apps Work" blog series that was specifically targeted at folks

Yes, it _was_ that bad. I worked on a Backbone app for multiple years. Integrated numerous plugins to try to fill various use cases (view lifecycles, event processing, computed data, UI composition). It was a _royal_ pain. React solved _al

The two of you are talking past each other :) Component _types_ are defined as either classes (`class MyComponent extends React.Component`), or functions (`function MyComponent(props) {}`). Internally, React has a "Fiber" data str

The simplest version is: - React has a module-scoped variable in the hooks implementation file that tracks which component is currently rendering - The internal "Fiber" data structure that describes a component instance has a link

Immer does a correct nested immutable update, same as if you wrote the corresponding nested spread operations by hand. It _only_ updates the nesting paths that led to the value that got modified. So yes, if you have a nested object with a

Deep cloning is almost never the right answer - you'll end up copying _too many_ object references, which is extra work, and that can also lead to unnecessary re-renders depending on what your components are trying to do. A correct imm

React _usually_ queues up a render, which is then executed at the end of the event loop tick. This allows many calls to `setState()` in the same tick to result in a single render pass at the end. The default behavior is that _if_ there are

Hi, I'm the current primary Redux maintainer, and have been since 2016, when Dan handed the maintainer keys to myself and Tim Dorr. I'm actually genuinely _not_ sure what you mean here. For clarity, the timeline was: - Summer 2015

Yeah, we specifically designed the listener middleware to do ~90% of what you could do in sagas, but with a smaller bundle size, simpler API, and better TS support: - https://redux-toolkit.js.org/api/createListenerMiddl

Glad to hear RTK is working well for you! FWIW, we actually specifically recommend _against_ using sagas in almost all cases. Instead, we recommend using our RTK Query API for data fetching and caching, and the RTK "listener" mi

The post is excellent (and I actually got quoted in there from my "Rendering Behavior" article), but the title seems completely over-editorialized? There's not even a mention of the word "fractal" in the post.

FWIW, that doesn't take into account that Next actually has its own wrapper around SWC, and also vendors it. I think it's probably the largest consumer of SWC: - https://github.com/vercel/next.js/tree&#x

That's not a "TypeScript" problem. That's a "JS being transpiled and bundled" problem (of which TS is just one possible example of "transpiling"). JS debuggers (browsers, VS Code, etc) normally use so

Yeah, data leakage is a concern in the sense that _everything_ about the process gets recorded. (At Replay, all the recordings are encrypted and access-controlled: https://www.replay.io/security-and-privacy ) The way Repla
