initMixin(Vue)->_init->$options-> $mount()当执行该挂载方法时DOM变化
initstate(vm)->initData()->proxy(vm,_data,key)代理函数
所以我们也可以同过this._data.dataName获取到数据
$mount->处理e（编译，转化成render函数）->mountComponent()->updateComponent()->渲染Wather
_render->从vm.options拿到render->render.call(vm._renderProxy,vm.$createElement)->initProxy->hasHandler判断元素如果不在target上，则会报错warnNonPresent-> 返回vnode
_update定义在src/core/instance/lifecycle.js （渲染）
vm.__patch__
patch
createPatchFunction ( 内部定义了一系列的辅助方法，最终返回了一个 patch 方法，这个方法就赋值给了 vm._update 函数里调用的
vm.__patch__)
函数柯里化
is属性，解决模板标签出现bug问题通过自动操纵transition中的元素的class实现
<link rel="stylesheet" href="./animate.css">
<script src="./vue.min.js"></script>
<style>
.fade-enter,.fade-leave-to{
opacity: 0;
}
.fade-enter-active,
.fade-leave-active{
transition: opacity 3s;
}
</style>
</head>
<body>
<div id="app">
<!-- type="transition" 放在transition里面指定指行的时间以animate或者transition为准-->
<transition
:duration="{enter: 5000, leave: 10000}"
name="fade"
appear
enter-active-class="animated swing fade-enter-active"
leave-active-class="animated shake fade-leave-active"
appear-active-class="animated swing"
>
