Summary: ## Context **Remote JS Debugging removal** In React Native 0.73, we have deprecated Remote JS Debugging (execution of JavaScript in a separate V8 process) and also removed the Dev Menu launcher (facebook#36754). This was motivated primarily by the broken state of this feature — in particular: incompatibility with the New Architecture. Secondly, as the React Native team continues to invest in improving debugging, we want to reduce the surface area of debugging modes that we support. During this year, we reached out to our partners about the impact of removing this feature, and if there was interest in having separate community support for debugging JSC on Android (a limited use case affected by this change). Without strong interest, we concluded that dropping Remote JS Debugging support in core for React Native 0.74 makes sense. We are focusing future debugging efforts into providing a first-class experience for Hermes. Existing alternatives: - [Direct debugging for JSC (Safari, iOS only)](https://reactnative.dev/docs/0.71/debugging#safari-developer-tools). - Direct debugging with Hermes: Flipper, [Chrome (old method)](https://reactnative.dev/docs/0.71/hermes#debugging-js-on-hermes-using-google-chromes-devtools), or via `react-native start --experimental-debugger` (intended future default). ## This diff This removes remaininng Remote JS Debugging code and `RCTWebSocketExecutor` on iOS.
