The Shared Element Transition feature allows for seamless animation of views between screens by using a shared transition tag.
This feature, though experimental, is designed to enhance user experience in applications by smoothing navigation transitions.

Reanimated 3 has a completely rewritten worklets/shared values engine and layout animations engine, focusing on improved performance and stability.
The rewrite enables new features like the Shared Element Transition and promises future updates leveraging the enhanced core structure.

Enhanced tools for developers include better error reporting through React Native’s LogBox and the ability to debug JavaScript directly in the UI runtime.
The introduction of the inline styles API simplifies coding, allowing direct mapping of shared values to UI component styles without boilerplate code.
The update is designed to maintain compatibility with the previous version, inherently facilitating easier migration for existing projects.
