* [be] Add deadlinks script (#7879)
While rewriting the compiler docs I happened to notice some deadlinks. This PR adds a new `yarn deadlinks` script to identify all deadlinks.
I decided to make this a script for now for simplicity but in the future could be ported to an ESlint rule.
The script handles:
- [x] checks images correctly (images are stored in /public but links can omit the /public)
- [x] looks up React error codes for dynamic error pages
- [x] lints links to contributors and uses URL from acknowledgements page if the member is no longer active on the core team
- [x] special injected anchor tags like #recap and #challenges
Example:
```
yarn run v1.22.22
$ node scripts/deadLinkChecker.js

* [compiler] Rewrite React Compiler Docs
We've received [feedback](https://bsky.app/profile/danabra.mov/post/3lr46ciujjs2r) that the compiler docs are difficult to understand and not prominent enough that people don't realize the compiler is a serious project and is near stable.
This PR rewrites the whole compiler doc section, giving it its own category as well as a standalone reference page.
Preview: https://react-dev-git-pr7868-fbopensource.vercel.app/
* [compiler] Fix misleading code example (#7889)
When the compiler bails out on code, it leaves it untouched and unoptimized, so it's always safe for the compiler to bailout.
`panicThreshold` in most cases should be kept as `'none'` unless you want to fail the build on these safe bailouts. It's really only useful during dev when you're working on increasing the coverage of the compiler on your codebase.
I think having it shown here is confusing so I'm opting to just remove it for this particular code example.
* [compiler] Flesh out incremental adoption intro more (#7890)
Previously the intro was pretty barebones. Fleshed it out a bit more to describe why it might be useful to reach for in a large codebase.
* [compiler] Add note about gating evaluation (#7891)
* [compiler] Flesh out incremental adoption intro more
Previously the intro was pretty barebones. Fleshed it out a bit more to describe why it might be useful to reach for in a large codebase.
* [compiler] Add note about gating evaluation
Clarify when the gating function is evaluated.
* Remove non-existent meetup group (Edinburgh, Scotland) (#7895)
The Edinburgh meetup group no longer exists and I have been unable to find any other Scottish React groups

Many React-based frameworks are full-stack and let your React app take advantage of the server. However, you can use the same approach even if you can't or don't want to run JavaScript on the server. In that case, serve the HTML/CSS/JS export ([`next export` output](https://nextjs.org/docs/advanced-features/static-html-export) for Next.js, default for Gatsby) at `/some-app/` instead.

- **Otherwise, consider using or building a client-side cache.** Popular open source solutions include [React Query](https://tanstack.com/query/latest), [useSWR](https://swr.vercel.app/), and [React Router 6.4+.](https://beta.reactrouter.com/en/main/start/overview) You can build your own solution too, in which case you would use Effects under the hood, but add logic for deduplicating requests, caching responses, and avoiding network waterfalls (by preloading data or hoisting data requirements to routes).

You can continue fetching data directly in Effects if neither of these approaches suit you.

@@ -26,11 +26,15 @@ There are two common cases in which you don't need Effects:
26
26
***You don't need Effects to transform data for rendering.** For example, let's say you want to filter a list before displaying it. You might feel tempted to write an Effect that updates a state variable when the list changes. However, this is inefficient. When you update the state, React will first call your component functions to calculate what should be on the screen. Then React will ["commit"](/learn/render-and-commit) these changes to the DOM, updating the screen. Then React will run your Effects. If your Effect *also* immediately updates the state, this restarts the whole process from scratch! To avoid the unnecessary render passes, transform all the data at the top level of your components. That code will automatically re-run whenever your props or state change.
27
27
***You don't need Effects to handle user events.** For example, let's say you want to send an `/api/buy` POST request and show a notification when the user buys a product. In the Buy button click event handler, you know exactly what happened. By the time an Effect runs, you don't know *what* the user did (for example, which button was clicked). This is why you'll usually handle user events in the corresponding event handlers.

You *do* need Effects to [synchronize](/learn/synchronizing-with-effects#what-are-effects-and-how-are-they-different-from-events) with external systems. For example, you can write an Effect that keeps a jQuery widget synchronized with the React state. You can also fetch data with Effects: for example, you can synchronize the search results with the current search query. Keep in mind that modern [frameworks](/learn/creating-a-react-app#full-stack-frameworks) provide more efficient built-in data fetching mechanisms than writing Effects directly in your components.

Handling race conditions is not the only difficulty with implementing data fetching. You might also want to think about caching responses (so that the user can click Back and see the previous screen instantly), how to fetch data on the server (so that the initial server-rendered HTML contains the fetched content instead of a spinner), and how to avoid network waterfalls (so that a child can fetch data without waiting for every parent).
