title: How to get "unfiltered" array items?
body: <p>Let's say I have an array which I filter by calling <code>myItems.filter(filterFunction1)</code> and get some items from it.</p>
  
  <p>Then I want to run another filtering function <code>filterFunction2</code> against the remaining items which were not selected by <code>filterFunction1</code>.</p>
  
  <p>Is that possible to get the remaining items that were left out after calling a filtering function?</p>
