我已经开始学习React出于好奇,想知道React和React Native之间的区别-虽然不能找到一个满意的答案使用谷歌。React和React Native似乎有相同的格式。它们的语法完全不同吗?

React is a framework for building applications using JavaScript. React Native is an entire platform allowing you to build native, cross-platform mobile apps, and React.js is a JavaScript library you use for constructing a high performing UI layer. React.js is the heart of React Native, and it embodies all React’s principles and syntax, so the learning curve is easy. The platform is what gave rise to their technical differences. Like the browser code in React is rendered through Virtual DOM while React Native uses Native API’s to render components on mobile. React uses HTML and with React Native, you need to familiarize yourself with React Native syntax. React Native doesn’t use CSS either. This means you’ll have to use the animated API which comes with React Native to animate different components of your application.
最重要的是,React是为你的web界面构建动态,高性能,响应性UI的理想选择,而React Native是为了给你的移动应用程序一个真正的原生感觉。

总结:React.js用于Web开发,而React-Native用于移动应用程序开发
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。

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
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。
