React 0.76 is now 15x faster
Here’s everything new that you need about the new version of React:
1/ 15x Faster Performance
+ React Native’s new setup offers 15x faster performance by optimizing how JavaScript and native code interact.
+ Eliminating delays lets React Native handle complex UI updates seamlessly.
2/ Bridge-Free Native Module System
+ The old bridge has been removed, allowing for direct, fast communication between JavaScript and native code.
+ This reduces startup time and improves runtime performance, with native calls now synchronous and type-safe.
3/ Multi-Threaded Rendering Engine
+ The New Renderer supports multi-threaded processing, prioritizing tasks like user input over other UI updates.
+ This enables React Native to handle high-demand UI tasks smoothly without UI lags or jank.
4/ Smarter Event Loop Management
+ React Native’s event loop now aligns with web standards, handling events and updates efficiently to prioritize user interactions.
+ This well-ordered event processing makes the user experience feel fluid and responsive.
5/ Automatic State Batching
+ State updates are now automatically batched, preventing unnecessary re-renders and improving overall app performance.
+ Developers benefit from faster UI updates without additional code adjustments.
6/ Concurrent Rendering Support
+ Full support for React’s concurrent features, like Suspense and Transitions, allows for smoother, non-blocking UI updates.
+ This makes it easier to manage complex UI elements and animations with minimal lag.
7/ Shared C++ Core Across Platforms
+ The new architecture shares a C++ core across all platforms, meaning consistent behavior across iOS, Android, and others.
+ Developers no longer need platform-specific tweaks for consistent UI performance.
8/ Enhanced Dev Tools and Debugging
+ Improved DevTools simplify error handling and debugging, especially for JavaScript crashes at startup.
+ These tools help streamline development and ensure high-quality app releases.
9/ Type Safety with Codegen
+ Codegen enforces type safety across JavaScript and native code, reducing cross-boundary errors.
+ This strong type-checking also enhances performance by minimizing common bugs in cross-platform development.
10/ Lighter, More Efficient Module Loading
+ Native modules are now loaded lazily by default, only when needed, which speeds up app startup.
+ This efficiency keeps the app lightweight, especially as complexity grows.
