title: How to mix namespaced mapGetters with global getters?
body: <p>I have namespaced one of my Vuex modules and I am unsure what syntax I should use for this scenario.</p>
  
  <p>I am currently using this syntax where <code>dealfilters</code> is my namespaced module.</p>
  
  <pre><code>...mapGetters('dealfilters', [
      'dealCount',
      'pending',
      'arrival',
      'nights',
      'tag',
      'sortOptions'
  ])
  </code></pre>
  
  <p>How would I go about adding a global getter for this mapgetter helper again? Or even call multiple different namespaced modules inside the mapGetter?</p>
