title: Vue.js: Is there a way to know when the component instance is mounted?
body: <p>Is there a boolean we can access in each component instance to know when a component is mounted?</p>
  
  <p>Something like:</p>
  
  <pre><code>&lt;template&gt;
    &lt;div&gt;
      &lt;span v-if="$mounted"&gt;I am mounted&lt;/span&gt;
      &lt;span v-if="$created"&gt;I am created&lt;/span&gt;
      &lt;span&gt;Called before created and mounted&lt;/span&gt;
    &lt;/div&gt;
  &lt;/template&gt;
  </code></pre>
