This is mostly true, You're absolutely right to compare it to React Fiber. So yes — it is revolutionary 🤯😏 but use cautiously, understand the limitations, and wait for full ecosystem support. 👍 |

Hi guy I recently joined GitHub and came across your project, and I’m really impressed by what you’re building. I specialize in community growth and marketing, and I’d love to contribute by helping you: Build and engage an active community around your project Create awareness through strategic promotion and outreach Attract new users and contributors to ensure long-term growth If this sounds valuable, I’d be happy to discuss ideas on how I can support your project. Looking forward to hearing from you |

Yep that's the core idea. The React Compiler statically analyzes your component code and automatically inserts the equivalent of useMemo, useCallback, and React.memo only where needed. |

he React Compiler is a new build-time optimization tool (currently in beta/Release Candidate) that automatically applies memoization and performance enhancements to your React components—meaning fewer unnecessary re-renders with greatly reduced boilerplate. It analyzes your code, recognizes dependencies, and transforms it to leverage internal caching hooks, reducing the need for manual tools like React.memo, useMemo, or useCallback. Under the hood, it injects a low-level hook (historically named _c or useMemoCache) to track dependencies and reuse previous renders when inputs haven’t changed—achieving behavior similar to manual memoization automatically. The compiler is safest in well-structured codebases that adhere to React’s rules. You can gradually adopt it by targeting specific directories, using its ESLint plugin for catching rule violations, and controlling opt-in/opt-out behavior via configuration directives. In React DevTools v5+, optimized components show a “Memo ✨” badge, making performance improvements visible. |

With React Compiler, React development can be done without having to manually consider useMemo, useCallback, or React.memo for performance optimization. Is my understanding correct?
If so, that sounds pretty cool—it's a revolutionary advancement on par with React Fiber.
