Add another item in javascript
<p>I am trying to add another item to the approval list below. I also want to make sure if the code is correctly formatted. </p>

<pre><code> function getApprovers() {
     //generate a list of approvers from APPROVAL_LISTS and APPROVALS_REQUIRED
     var approvers = [];
     if (item.APPROVALS_REQUIRED !== null) {
         approvers = item.APPROVALS_REQUIRED;
     }
     if (item.APPROVAL_LISTS !== null) {

         //I am trying to add another item here for example Tools_APPROVAL_LISTS,              //What is the correct way to do this. 
         approvers = approvers.concat(item.APPROVAL_LISTS.APPROVALS_REQUIRED);
     }
     approvers = getUnique(approvers);
     return approvers;
 }
</code></pre>
