於 React 與 Facebook 的 JavaScript 函式庫，用以建構使用者界面，但相較於以瀏覽
器為目標，它的目標是行動平台。換句話說：網頁開發者現在可以用我們已經熟知的
JavaScript 函式庫撰寫觀感上真正“原生”的行動應用程式。還有，因為大部分你所撰
寫的程式可以跨平台共用，React Native 讓同時開發 Android 與 iOS 變得簡單。
類似網頁用的 React，React Native 應用程式以 JavaScript 與稱為 JSX 的 XML 標籤混合
撰寫。然後 React Native 在底層以 Objective-C（iOS）或 Java（Android）“橋接”原生
API 的呼叫。因此，你的應用程式會使用真正的行動 UI 元件而
非
網頁元件，其外觀與
操作感會與其他行動應用程式相似。React Native 還有顯露出 JavaScript 的平台 API 界
面，因此你的 React Native 程式可存取相機或位置等平台功能。
React Native 現在支援 iOS 與 Android 且有潛力擴展至未來的平台。本書內容涵蓋 iOS
