title: Access data object in asyncData - Nuxt
body: <p>I wonder if there is a way to access object properties as keys returned by asyncData()?</p>
  
  <pre><code>data() {
      return {
         bookmark_btn: {
          status: null,
          loading: false
        }
     }
  }
  </code></pre>
  
  <p>I tried access data object properties like below but didn't work.</p>
  
  <pre><code>async asyncData(){
      let activity = await axios.get('data.json')
      return { bookmark_btn.status: activity.status}
  }
  </code></pre>
