Let me write it all down, it's a bit confusing. There is a React framework, created to produce Javascript backed applications running in the browser. Then there is a React Native, a wrapper to run those applications on mobile platforms by compiling Javascript apps to native code. And then here is a React Native for Web, a way to compile a Javascript React Native apps into... Javascript to run inside browsers?

Boy, that frontend ecosystem is really cursed.

React Native web is really all about code sharing between web and mobile in my mind. Say Twitter were to build their website in plain ReactJS, if they did that then there would be no easy way to transfer components from web to mobile, yes they are both written in React, but regular React isn't 100% interoperable with React Native.

This is where React Native for Web comes into the picture, RN for Web patches that gap of interoperability between web and mobile, what Twitter likely has behind the scenes is a custom UI library that provides all the elements you see on Twitter, if they had chosen ReactJS for the web, they would have to maintain two libraries, however with React Native for web, they only have to maintain one.
