title: How to reference data variable from another data variable in Vue 2?
body: <p>I have this in vue data:</p>
  
  <pre><code>data() {
      return {
  
        names: [],
        length: names.length,
  }
  </code></pre>
  
  <p>But this does not work as RefereneError ( names is undefined ) is thrown. I used this.names but makes no difference.</p>
