React is used for creating websites, web apps, SPAs etc. React is a Javascript library used for creating UI hierarchy. It is responsible for rendering of UI components, It is considered as V part Of MVC framework. React’s virtual DOM is faster than the conventional full refresh model, since the virtual DOM refreshes only parts of the page, Thus decreasing the page refresh time. React uses components as basic unit of UI which can be reused this saves coding time. Simple and easy to learn. React Native React Native is a framework that is used to create cross-platform Native apps. It means you can create native apps and the same app will run on Android and ios. React native have all the benefits of ReactJS React native allows developers to create native apps in web-style approach.

React Js是一个Javascript库，你可以使用React开发和运行更快的web应用程序。

React Native让你只使用JavaScript构建移动应用程序，它用于移动应用程序开发。更多信息请点击这里https://facebook.github.io/react-native/docs/getting-started.html

简单地说，React和React native遵循相同的设计原则，除了在设计用户界面的情况下。

React本机有一组单独的标记来定义user 但是两者都使用JSX来定义组件。 这两个系统的主要目的是开发可重用的ui组件，并通过其组合减少开发工作。 如果你正确地规划和构建代码，你可以在移动和web上使用相同的业务逻辑

无论如何，它是一个为移动和网络构建用户界面的优秀库。

React-Native是一个跨平台的应用程序，使用reactjs为所有平台(iOS, Android, Web, Windows, Mac, Linux)构建相同的代码。

实现上的区别在于reactjs使用HTML标记，而react-native使用react-native特定的组件。

为了回应上面@poshest的评论，这里有一个React Native版本的时钟代码，之前在React中发布(抱歉，我无法直接评论这部分，否则我会在那里添加代码):

React Native代码示例

import { AppRegistry } from 'react-native';
import React, { Component } from 'react';
import { View, Text, StyleSheet } from 'react-native';

class Clock extends Component {
  constructor(props) {
    super(props);
    this.state = { date: new Date() };
  }

  componentDidMount() {
    this.timerID = setInterval(
      () => this.tick(),
      1000
    );
  }

  componentWillUnmount() {
    clearInterval(this.timerID);
  }

  tick() {
    this.setState({
      date: new Date()
    });
  }

  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.sectionTitle}>Hello, world!</Text>
        <Text style={styles.sectionDescription}>It is {this.state.date.toLocaleTimeString()}.</Text>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    backgroundColor: 'white',
    flex: 1,
    justifyContent: 'center',
  },
  sectionTitle: {
    fontSize: 24,
    fontWeight: '600',
    color: 'black',
    alignSelf: 'center',
  },
  sectionDescription: {
    marginTop: 8,
    fontSize: 18,
    fontWeight: '400',
    color: 'darkgrey',
    alignSelf: 'center',
  },
});

AppRegistry.registerComponent("clock", () => Clock);

注意，样式完全是我的选择，并不寻求直接复制在React代码中使用的<h1>和<h2>标记。
