这是一个混合工具的应用程序开发的操作系统和android。你不需要写两次代码。 它使用本地组件和react。 它还为您提供了访问服务器(firebase)的权限。 如需进一步帮助，请点击以下链接: https://reactnative.dev/ https://nativebase.io/

一个简单的比较应该是

反应Js

return(
    <div>
      <p>Hello World</p>
    </div>
)

反应本地

return(
    <View>
      <Text>Hello World</Text>
    </View>
)

React Native没有像div, p, h1等Html元素，相反，它有对移动设备有意义的组件。 详情见https://reactnative.dev/docs/components-and-apis

React Native是为移动应用程序，而React是为网站(前端)。这两个框架都是Facebook发明的。React Native是一个跨平台的开发框架，这意味着你可以为IOS和Android编写几乎相同的代码，而且它可以工作。我个人对React Native了解更多，所以我就到此为止。

我们无法准确地比较它们。用例中存在差异。

React的主要关注点是Web开发。

React’s virtual DOM is faster than the conventional full refresh model, since the virtual DOM refreshes only parts of the page. You can reuse code components in React, saving you a lot of time. (You can in React Native too.) As a business: The rendering of your pages completely, from the server to the browser will improve the SEO of your web app. It improves the debugging speed making your developer’s life easier. You can use hybrid mobile app development, like Cordova or Ionic, to build mobile apps with React, but is more efficiently building mobile apps with React Native from many points.

React的扩展，针对移动开发。

Its main focus is all about Mobile User Interfaces. iOS & Android are covered. Reusable React Native UI components & modules allow hybrid apps to render natively. No need to overhaul your old app. All you have to do is add React Native UI components into your existing app’s code, without having to rewrite. Doesn't use HTML to render the app. Provides alternative components that work in a similar way, so it wouldn't be hard to understand them. Because your code doesn’t get rendered in an HTML page, this also means you won’t be able to reuse any libraries you previously used with React that renders any kind of HTML, SVG or Canvas. React Native is not made from web elements and can’t be styled in the same way. Goodbye CSS Animations!

希望我帮到你了:)

React和React-native之间的主要区别是React带有基于Web的UI组件，而React native则带有与移动相关的UI小部件，其余一切几乎相似。

简单来说 ReactJS是父库，它返回一些东西来渲染每个主机环境(浏览器，移动，服务器，桌面等)。 除了渲染，它还提供了其他方法，如生命周期钩子..等。

在浏览器中，它使用另一个库react-dom来呈现DOM元素。 在移动端，它使用React-Native组件来呈现特定平台(IOS和Android)的本地UI组件。 所以,

React + React -dom = web开发

React + React -native =移动开发
