title: resolved in async component?
body: <p>I had read the acticle <a href="https://ssr.vuejs.org/en/data.html#client-data-fetching" rel="nofollow noreferrer">Client Data Fetching</a> in Vue.js SSR<br/></p>
  <pre><code>router.onReady(() =&gt; {
   // Add router hook for handling asyncData.
   // Doing it after initial route is resolved so that we don't double-fetch
   // the data that we already have. Using `router.beforeResolve()` so that all
   // async components are resolved.
   router.beforeResolve((to, from, next) =&gt; {
   // ....
  </code></pre>
  <p>there is one statement says :</p>
  <blockquote>
  <p>Using <code>router.beforeResolve()</code> so that all async components are
  resolved</p>
  </blockquote>
  <p>what is the meaning of &quot;async components are resolved&quot;?</p>
