恭喜你完成了 React 和 Redux 的所有课程!在继续前进前,还有一点值得我们注意。通常,我们不会在这样的编辑器中编写 React 应用代码。如果你在自己的计算机上使用 npm 和文件系统,这个挑战可让你一瞥 React 应用的语法之貌。除了使用<code>import</code>语句(这些语句引入了各挑战中提供的所有依赖关系),其代码看起来类似。“管理包(含 npm)”这一节更详细地介绍了 npm。

|
|
|
|
|
最后,写 React 和 Redux 的代码通常需要一些配置,且很快会变得复杂起来。如果你想在自己的机器上尝试写代码,点击链接

|
|
|
|
另一种做法是在 CodePen 中启用 Babel 作为 JavaScript 预处理器,将 React 和 ReactDOM 添加为外部 JavaScript 资源,在那里编写应用。
