title: vuejs auto-filter out an array marked "Bar"
body: <p>I am new vuejs but learning a lot. I Have an array of items that renders to a list perfectly fine. I do want to not display anything marked Bar? I have tried !Bar but it does not work. Whats the correct way to do this?</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>var app = new Vue({
    el: "#demo",
    data: {
      items: [{
        childMsg: 'Foo'
      }, {
        childMsg: 'Bar'
      }]
    }
  });</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://unpkg.com/vue"&gt;&lt;/script&gt;
  
  &lt;div id="demo"&gt;
    &lt;ul v-for="item in items"&gt;
      &lt;li&gt;{{item.childMsg}}&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
