The async nature of the React Native bridge incurs an inherent performance penalty. This traditionally prevents JavaScript code from running at high framerates. One of the most noticeable challenges is animations in JavaScript, which arent guaranteed to run at 60 FPS.

Modern animation libraries for React Native, like Animated, tackle this challenge with a declarative approach. In order to minimize passes over the bridge, animations are only declared in JavaScript but executed by a native driver on the other side - in 60 FPS.

Fluid user interactions take this a step further than animations. Interactions require UI to continuously react to the users gestures. This library is designed to support complex physical interactions with ease, using a full-fledged physics engine to drive the interaction on the native side.
