10. what does "Hydration failed because the initial UI does not match what was rendered on the server" mean? a hydration issue refers to a problem that arises when the initial HTML rendered on the server does not match the structure React expects on the client.

9. How do React Server Components improve performance by streaming content? React Server Components allow the rendering process to be divided into manageable chunks, which are then streamed to the client as soon as they are ready

8. what is the difference between RSC and SSR? React Server Components are always rendered on the server, fetching data colocated with rendering, while Server-Side Rendering sends HTML to the client initially, then loads React JavaScript for client-side functionality

7. How do you assign component state for rendering in React Server Components without using useState and useEffect? In React Server Components, where useState might not be supported, managing component state for rendering can be achieved through alternative state management lib.

6. How can server-side components communicate with client-side components in React? Server-side components can communicate with client-side components in React by passing data or events between them using props or other communication patterns like context or custom events

5. How to use Suspend with RSC? Suspense can be used in server components to handle asynchronous operations smoothly in React. You can wrap your components that require asynchronous data loading with the Suspense component to manage the loading state and fallback UI

4. Why can React Server Actions be imported into Client components, and not vice versa? RSA can be imported into Client components due to the nature of server-side rendering and the way components are loaded and executed, which allows server actions to be utilized in client-side

3. How can I access the URL pathname in a server component in Next.js? To access the URL pathname in a server component in Next.js, you can't use window.location directly. Instead, you need to find an alternative method within the server-side context

2. How do React Server Components impact SEO compared to SSR/Next.js? React Server Components, being rendered on the server dynamically, can positively affect SEO by improving page load times and content indexing

1. What are React Server Components? React Server Components are a subset of React.js that allows loading components from the backend, where the components are pre-rendered and seamlessly integrated into the running app

10/10 Conclusion: Embracing React 19: React 19 brings exciting improvements like the new compiler, reconciliation enhancements, strict mode checks, and hydration changes. Stay current with React's evolution for faster, more scalable apps.

9/10 Deprecated APIs and Breaking Changes: Handle breaking changes by reviewing the changelog, using deprecation warnings, trying codemods, setting up staging environments, and leaning on the community for support.

7/10 Transitioning from Render-Props to Hooks: Hooks offer advantages like readability, reuse, avoidance of wrapper hell, and flexible composition. Refactor gradually, extract custom hooks, and update tests.

6/10 Reconciliation and Rendering Advancements: React 19 minimizes rerenders with granular updates, embraces asynchronous rendering, improves hydration, updates lifecycle methods, and enhances developer experience with strict mode checks.
