由於高度封裝與抽象，JavaScript 的執行效率比不上 C 的語言。例如 JavaScript 的 Array 下標（subscript）是根據 hash key 而非實體記憶體位址 offset 取值，雖然方便，卻多了效能開銷。當 Canvas、WebGL、WebVR 開始走紅，效能越來越受重視，如何讓 JavaScript 達到如同 C 指標般操作 binary data 變得至關重要。
存在許久但最近才變為 ES6 標準「Typed Array」就是解放 JavaScript 操作 binary data 能力的好工具！一起來了解 Typed Array 吧！

About two month ago, I started making a React Native app ["PyConTW 17"][pycontw-mobile] for the biggest annual Python conference in Taiwan ([PyCon Taiwan][pycontw]). The app is quite simple, but still took some efforts for me to build. As a complete React newbie, I would like to share some of my thoughts about React Native.
