 Now that we have data fetching pretty well sorted, we're exploring the other direction: sending data from the client to the server, so that you can execute database mutations and implement forms. We're doing this by letting you pass Server Action functions across the server/client boundary, which the client can then call, providing seamless RPC. Server Actions also give you progressively enhanced forms before JavaScript loads.

There's a clear separation for features provided by the RSC spec and implementation. React Server Components is meant as a spec for components that work across compatible React frameworks.
 
 We generally recommend using an existing framework, but if you need to build your own custom framework, it is possible. Building your own RSC-compatible framework is not as easy as we'd like it to be, mainly due to the deep bundler integration needed. The current generation of bundlers are great for use on the client, but they weren't designed with first-class support for splitting a single module graph between the server and the client. This is why we're now partnering directly with bundler developers to get the primitives for RSC built-in.

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

@@ -26,7 +26,7 @@ There are two common cases in which you don't need Effects:
 * **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.
 * **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/start-a-new-react-project#production-grade-react-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).

-- By default, `setState` updates immediately and does not activate `<ViewTransition>`, only updates wrapped in a [Transition](/reference/react/useTransition). You can also use [`<Suspense>`](/reference/react/Suspense) to opt-in to a Transition to [reveal content](/link-to-suspense-below).
+- By default, `setState` updates immediately and does not activate `<ViewTransition>`, only updates wrapped in a [Transition](/reference/react/useTransition). You can also use [`<Suspense>`](/reference/react/Suspense) to opt-in to a Transition to [reveal content](/reference/react/Suspense#revealing-content-together-at-once).
 - `<ViewTransition>` creates an image that can be moved around, scaled and cross-faded. Unlike Layout Animations you may have seen in React Native or Motion, this means that not every individual Element inside of it animates its position. This can lead to better performance and a more continuous feeling, smooth animation compared to animating every individual piece. However, it can also lose continuity in things that should be moving by themselves. So you might have to add more `<ViewTransition>` boundaries manually as a result.
 - Many users may prefer not having animations on the page. React doesn't automatically disable animations for this case. We recommend that using the `@media (prefers-reduced-motion)` media query to disable animations or tone them down based on user preference. In the future, CSS libraries may have this built-in to their presets.
 - Currently, `<ViewTransition>` only works in the DOM. We're working on adding support for React Native and other platforms.

-If your app uses server rendering (either [directly](/reference/react-dom/server) or via a [framework](/learn/start-a-new-react-project#production-grade-react-frameworks)), your component will render in two different environments. On the server, it will render to produce the initial HTML. On the client, React will run the rendering code again so that it can attach your event handlers to that HTML. This is why, for [hydration](/reference/react-dom/client/hydrateRoot#hydrating-server-rendered-html) to work, your initial render output must be identical on the client and the server.
