Summary: ## Stack These can suss out some real bugs, and helps further avoid mismatch with downstream MSVC on /W4 as used by MSFT. I enabled the families of warnings, but suppressed some major individual warnings that weren't clean. But I did clean some up, notably, missing initializer, and shortening 64 bit to 32 bit. We can do some of the rest incrementally (e.g. `-Wunused-parameter` has a fixit). This change illuminates that MapBuffer is missing 64 bit integer support, but we often pass 64 bit counters to it, which is a bug. For now I just left TODOs around those. `rn_xplat_cxx_library` is used for external libraries interfacing with RN, which we probably don't want to police, so I structured these stricter warnings as an opt-in flag, only enabled for our own rules. ## Diff This fixes up source code to avoid emitting the extra warnings now enforced. Of what is enabled, this is mostly shortening 64 to 32, or missing field in initializer.

React Native
Learn once, write anywhere:
Build mobile apps with React.
Getting Started · Learn the Basics · Showcase · Contribute · Community · Support
React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
- Portability. Reuse code across iOS, Android, and other platforms.
React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements
React Native apps may target iOS 13.4 and Android 6.0 (API 23) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this.
🎉 Building your first React Native app
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
📖 Documentation
The full documentation for React Native can be found on our website.
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
The source for the React Native documentation and website is hosted on a separate repo, @facebook/react-native-website.
🚀 Upgrading
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.
React Native releases are discussed in this discussion repo.
