What's the real deal with React Native's cross-platform support? Does it only work for iOS and Android, or does it extend to the web as well? How much of a performance boost does it actually provide? A bit confused here, any clarification would be appreciated.
Is React Native really cross-platform?

React Native isn’t *just* cross-platform in the traditional mobile sense—it’s broader than that. While it’s primarily focused on iOS and Android, it’s expanded into the web thanks to **React Native for Web**, allowing you to run the same codebase on both mobile and desktop. On iOS and Android, it leverages native components for optimized performance, while on the web, it renders to the DOM. So yes, it adapts to different platforms, but it’s not *exactly* the same everywhere—some UI components may still need platform-specific tweaks.
If we’re talking performance, React Native has its advantages over **Flutter** or **hybrid solutions** like Cordova. Since it bridges directly to native components, it performs almost like a fully native app—especially on iOS and Android. Flutter, on the other hand, uses its own rendering engine, which gives it more consistent performance across platforms, but React Native’s learning curve and ecosystem are more mature. On the web, React Native for Web can be limited by its reliance on the DOM—complex animations, for example, might not perform as well as Flutter or a fully native solution.
So, in short: React Native *is* cross-platform, but it’s not equally optimized for *every* platform.
