|  | 恭喜! 你完成了 React 和 Redux 的所有課程! 結束之前,還要再提一點。 通常,我們不會在這樣的編輯器中編寫 React 應用代碼。 如果你在自己的計算機上使用 npm 和文件系統,這個挑戰可讓你一瞥 React 應用的語法之貌。 除了使用 `import` 語句(這些語句引入了各挑戰中提供的所有依賴關係),其代碼看起來類似。 “管理包(含 npm)”這一節更詳細地介紹了 npm。 | |||
|  | 
 | |||
|  | 最後,寫 React 和 Redux 的代碼通常需要一些配置, 且很快會變得複雜起來。 如果你有興趣在自己的電腦上嘗試,<a href="https://github.com/facebookincubator/create-react-app" target="_blank" rel="nofollow">Create React App</a> 已配置好,並準備就緒。 | |||
|  | 
 | |||
|  | 或者,你可以在 CodePen 中啓用 Babel 作爲 JavaScript 預處理器,將 React 和 ReactDOM 添加爲外部 JavaScript 資源,這樣編寫應用。 | |||

|  | 在控制檯輸出消息 `'Now I know React and Redux!'`。 | |||

 | |||
|  | 
 | |||
|  | 應該將 `Now I know React and Redux!` 這一消息應輸出到控制檯。 | |||
|  | 
 | |||
|  | ```js | |||
|  | (getUserInput) => | |||
|  |   assert( | |||
|  |     /console\s*\.\s*log\s*\(\s*('|"|`)Now I know React and Redux!\1\s*\)/.test( | |||
|  |       getUserInput('index') | |||
|  |     ) | |||
|  |   ); | |||
|  | ``` | |||
