⭐️React Native 0.76 with New Architecture⭐️

The New Architecture adds full support for modern React features, including Suspense, Transitions, automatic batching, and useLayoutEffect. The New Architecture also includes new Native Module and Native Component systems that let you write type-safe code with direct access to native interfaces without a bridge.

The New Architecture includes four main parts:
🔹 Synchronous Native Modules:
Type-safe access to native code without the bridge, written in C++ for speed and cross-platform compatibility.

🔹 New Renderer:
Multiple threads allow updates at various priorities, improving responsiveness and reducing jank.

🔹 Event Loop:
Prioritizes urgent updates, aligns with web standards, and lays the groundwork for browser features like microtasks and IntersectionObserver.

🔹 Bridge Removed:
Faster startup and enhanced performance by enabling direct JavaScript-native communication.

⭐️Exploring the Power of the Reflect Object in JavaScript and Its Role in Nest.js Decorators⭐️

- The Reflect object in JavaScript is a versatile built-in object that allows developers to perform meta-programming tasks and interact with object properties and methods in a standardized way. It's particularly useful in frameworks like Nest.js, where it plays a critical role in enabling decorators.

- Nest.js leverages the reflect-metadata library, which works in tandem with the Reflect object to manage and retrieve this metadata.

🔍 React has its own MurmurHash3 implementation… and it’s hidden in plain sight!

Inside the React source code, there's a little gem of an implementation tucked away in createFastHashJS.js. This file contain a pure JavaScript, Sync, non-cryptographic hashing function based on MurmurHash3 (32-bit).

export function createFastHashJS(key: string): number {
  return murmurhash3_32_gc(key, 0);
}

❓Why does React need this ?
React uses this fast hash internally —- for example, to hash key paths used in useActionState when handling MPA-style from submissions.
These hashes are used to track state transitions, cache component branches, or generate unique keys.

❓Why not use Web Crypto?
The browser’s crypto.subtle.digest() is asynchronous, which makes it unsuitable in React performance-critical paths where synchronous execution is essential to avoid choppy renders and high context-switching costs.

✅ MurmurHash3: The best choice
This version comes from Gary Court's highly respected JS port of the MurmurHash3 algorithm.

📦 Use Cases in environments like React.
- Component key path hashing.
- Action state deduplication.
- Deterministic memoization cache keys.
- Static asset naming (in build tools).
- ID generation in SSR contexts.

🔐 Important warning
This hash is not cryptographically secure. It’s optimized for speed and determinism, not protection. Don’t use it for passwords, tokens, or anything sensitive!

✨ This is one of those internal utilities that reminds us: even in massive projects like React, simplicity often wins when performance is king 👑
