Angular 2 網站開發框架 多奇數位創意有限公司 技術總監 黃保翕 ( Will 保哥 ) 部落格：http://blog.miniasp.com/ 適用 Angular 2.0.0-rc.5 版本 我們所認識的前端技術都是假的 千萬不要執著你之前學會的任何技術 忘掉一切的業障 才有重生的機會 今天我們要來 重新認識 Angular 2 開發框架 記得：今天是來消除業障的！ 比 Angular 1 更好 • 速度更快 – 偵測變更：比 ng1 快 10 倍 – 渲染速度：比 ng1 快 5 倍 (Render & Re-render) • 範本編譯：支援 Template 預先編譯機制 – 更小的 Library Size ( 透過 webpack 自動合併 ) – 支援延遲載入機制與伺服器渲染機制 (Node.js & ASP.NET ) • 學習曲線更低 2.0 ES 2015 ES5 Angular 2 的開發語言 • ES5 – 傳統 JavaScript 程式語言 ( IE9+ ) • ES 2015 – 此版本為 ES5 的「超集合」 – 具有新穎的 JavaScript 語言特性 ( let, const, for-of, … ) – 可透過 Babel 轉譯器將瀏覽器不支援的語法轉為 ES5 版本 • TypeScript
