javascript - The dom generated by vue is a bit strange. It is nested when written and at the same level when generated.

<body>
  <p id="app">
    <p class="con1" @click="click">
      vue
      <p class="con2"></p>
    </p>
  </p>
  <script>
    var vm = new Vue({
      el: '#app',
      mounted() {
        for (let i of this.$el.children) {
          console.log(i)
        }
      },
      methods: {
        click() {
          for (let i = 0; i < this.$el.children.length; i++) {
            console.log(this.$el.children[i])
          }
        }
      }
    })
  </script>
</body>

It is obviously nested, but after generation it is the same level
