React Native Worklets

React Native Worklets is a fundamental library providing low-level multithreading capabilities for React Native applications. It enables JavaScript functions, known as 'worklets', to execute directly on the UI thread or other background threads, bypassing the JavaScript thread bottleneck. This is crucial for achieving smooth animations, gestures, and other performance-sensitive operations that might otherwise cause UI jank. The library is closely integrated with and often used as a core component of `react-native-reanimated`. The current stable version is 0.8.1, with releases often coinciding with major `react-native-reanimated` updates. A key differentiator is its `Shareable` memory type, introduced in v0.8.0, which allows for efficient and safe data sharing between threads. It focuses on raw performance and thread control, rather than high-level animation APIs, serving as a building block for more complex libraries.
