React Fiber documentation not present in the current Docs

The current React documentation does not include detailed information about React Fiber. Given the importance and impact of React Fiber on React's performance and internal mechanisms, it would be beneficial for developers to have comprehensive documentation on this topic.

Proposed Content:

1. Introduction to React Fiber
2. How React Fiber differs from the previous reconciliation algorithm
3. Benefits of React Fiber
4. How React Fiber works (including concepts like work loops, priority levels, and interruption)
5. Examples and use cases demonstrating React Fiber's advantages

Rationale:
Having thorough documentation on React Fiber will help developers understand the underlying architecture of React, enabling them to write more efficient and optimized applications. It will also aid in debugging and enhancing their knowledge of React's performance improvements.

Additional Information:
If there are any existing resources or blog posts that can be referred to in the meantime, it would be helpful to include those as well.

Aucun fichier, test ou point d’entrée précis de la documentation n’est indiqué. Commencez par examiner la documentation actuelle de React ainsi que les ressources ou articles de blog existants mentionnés dans l’issue. Le travail sera considéré comme terminé lorsque les cinq domaines proposés seront couverts de manière exhaustive, notamment l’architecture de Fiber, les différences de réconciliation, les avantages, les work loops, les priorités, l’interruption et les exemples.
