• ref(param) === reactive({value: param})
• ref和reactive都为递归监听
• 如果在template自动使用ref数据的时候，会自动添加value属性

<template>
  <div class="page-wrapper">
    <p>--------------------------ref和reactive的关系---------------------</p>
    <p>{{stuAge}}</p>
    <button @click="myFn">点我一下,agg++</button>
    <p>{{refData}}</p>
    <button @click="refFn">点我一下,refChange</button>
    <p>{{reactiveData}}</p>
    <button @click="reactiveFn">点我一下,reactiveChange</button>
  </div>
</template>
