vue框架入門和ES6介紹
vue-mvvm模式，vue是一種輕量級的前端框架，主要為模板渲染，數據同步，組件化，模塊化，路由等。
https://cn.vuejs.org/ 源碼：https://github.com/vuejs/vuemvvm: m為model數據模型，負責數據存儲，v為view視圖，負責頁面顯示，vm為view model負責業務處理。
數據雙向綁定：
view <-> viewmodel <-> model

模塊化，塊級作用域，箭頭函數等。
什麼是JavaScript，它是一種動態類型，弱類型的腳本語言，用來給HTML網頁增加的動態功能。
JavaScript由三部分組成：
ECMAScript（核心）DOM（文檔對象模型）BOM（瀏覽器對象模型）
let是聲明變數的關鍵字
