title: How to use mapGetters when Vue CDN is used?
body: <p>I'm trying to use mapGetters from Vue.js but instead use NPM to install I used Vue CDN like this:</p>
  
  <pre><code>&lt;script src="https://unpkg.com/vuex@3.0.1/dist/vuex.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I can't do the import as usual: </p>
  
  <pre><code>import {mapGetters} from 'vuex';
  </code></pre>
  
  <p>And neither use mapGetters without import.</p>
  
  <pre><code>export default {
  computed: mapGetters([
    'doubleCounter',
    'realCounter'
  ])}
  </code></pre>
  
  <p>How can I use mapGetters using Vue CDN?</p>
