tl;dr React Native doesn't use browser.
It's not clear from your comment whether you're familiar with React Native architecture or not. A React Native app works by using JS/React as the "brains" of the app (http services, state, smart components) and runs this in a separate thread to a 100% native portion of the app that uses uses platform specific native ui controls. Animation performance is pretty good because of this multithreaded approach. So in this way your JS app brain can be portable across platforms, while the nitty gritty view layer may shift to accommodate the capabilities of the native components you work with on each platform.
