第一次接触神奇的前端框架vue.js

入手2016最火前端框架之一vue.js。大概从网上找了些资料看了下vue.js,从网上的资料来看只能惊叹其发展速度太快,让我意外的是其作者是华人的前提下作品这么受欢迎。 网上的博客和教程各种组合。以至于我都有些感觉out。各种vue+webpack、vue+react、vue+es6+npm等等。琳琅满目。真是三天不学习赶不上刘少奇。

开篇主要是初次了解下vue.js,包括v-model、v-if、v-else、v-show、v-for(2.0对$index和$key舍弃,2.0要用index属性语法为  v-for="(person,index) in persons")、v-on。
