为什么Android要申请权限

Learning React
A hands-on guide to building web applications using React and Redux
As far as new web frameworks and libraries go, React is quite the runaway success. It not only deals with the most common problems developers face when building complex apps, it throws in a few additional tricks that make building the visuals for such apps much, much easier.
What React isn’t, though, is beginner-friendly and approachable. Until now. In Learning React , author Kirupa Chinnathambi brings his fresh, clear, and very personable writing style to help web developers new to React understand its fundamentals and how to use it to build really performant (and awesome) apps.
The only book on the market that helps you get your first React app up and running in just minutes, Learning React is chock-full of colorful illustrations to help you visualize difficult concepts and practical step-by-step examples to show you how to apply what you learn.

一个友好的应用程序管理器和React.js的任务运行器
React Web开发中有许多“元”技能与构建出色的Web产品并没有任何关系。
例如终端。 对于那些没有在unix外壳上长大的人来说，终端是一个难以理解的盒子，其中包含难以理解和难以理解的命令。 它无疑是强大的，并且是开发的宝贵技能……但是它真的应该成为现代Web开发的先决条件吗？
Guppy是一个免费使用的桌面应用程序，旨在使您更轻松地开始构建React Web产品。 它为React开发人员面临的许多典型任务提供了友好的GUI：
创建新项目
运行开发服务器
