title: Adding functions to redux store within reducer is an anti pattern?
body: <p>say I have a component connected to the redux store. Within this store, there's a list of objects. For instance something like this:</p>
  
  <pre><code>ReduxStore: {
      dataList: [
        {name:'bla'},
        {name:'blub'},
      ]
  }
  </code></pre>
  
  <p>Is it actually an anti pattern to create and add a filter function within the reducer to  create something like this:</p>
  
  <pre><code>ReduxStore: {
     dataList: {
       data:[
        {name:'bla'},
        {name:'blub'}
       ],
       isNameAvailable: (name) =&gt; {/* search for name */}
     }
  }
  </code></pre>
  
  <p>It works great, but I'm not sure whether this was the intended way to go.</p>
