请教个slot-scope 命名问题

父组件

<div style="width:100%;height:auto;background:red">
    <slot :default="nav"></slot>
</div>
data() {
  return {
    nav:[]
  }
},
methods:{
    this.$post('Mobile', {}).then((res) => {
      this.nav = data.preHeatContent;
    })
}

子组件

<child>
  <template slot-scope="bbb">
    {{bbb}}
  </template>
</child>

问题一
父组件里 <slot :default="nav"></slot> 这个default的名字是自己随便取名 并且和 子组件的 slot-scope = 的这个名字 不相关吗?
问题二
子组件 slot-scope="bbb" 这个bbb也是自己随便取的名 和 父组件slot的名字也不相关吗?
