title: Create an array from it's looped values
body: <p>I created a filter to retrieve the objects from an array. Made use of some of the object values but now I want to use the ids as an array not individually. I know pushing isn't right in this case and since I am still within the filter, how do I achieve this, please?</p>
  
  <pre><code>arrayList = [
    {
       id: 48589,
       height: 5.8,
       active: false
    },
    {
       id: 84697,
       height: 4.6,
       active: true
    },
   {
       id: 887697,
       height: 5.0,
       active: true
     }
   ]
  
   arrayList.filter(c =&gt; {
      if(c.active){
       //`I used the other values here
      } else {
      //Now I need c.id as an array to search my db
  
         ids = [];
         ids.push(c.id)
      }    
   })
  </code></pre>
