Native Bridge

Definitions

1. The interop layer in cross-platform frameworks like React Native that serializes calls between the JavaScript runtime and the native platform APIs (Objective-C/Swift on iOS, Java/Kotlin on Android), enabling JS code to invoke camera, GPS, or other device capabilities at the cost of serialization overhead.

   In plain English: The translation layer that lets code written in one language (like JavaScript) talk to the phone's built-in features that are written in a different language.

   Example: "The animation jank was caused by too many calls crossing the native bridge — we moved the interpolation to the native side with Reanimated."
