title: jquery combining multiple arrays
body: <p>I'm currently doing the following to combine a number of Jquery Arrays and put the data back into the DOM - this works fine:</p>
  
  <pre><code>conversationsInBoxMemberUserIDsArrayTemp = $.merge(conversationsInBoxMemberUserIDsPinnedArray,conversationsInBoxMemberUserIDsNewReplyArray);
  conversationsInBoxMemberUserIDsArrayTemp2 = $.merge(conversationsInBoxMemberUserIDsArrayTemp,conversationsInBoxMemberUserIDsOldReplyArray);
  conversationsInBoxMemberUserIDsArrayFinal = $.merge(conversationsInBoxMemberUserIDsArrayTemp2,conversationsInBoxMemberUserIDsNeverReplyArray);
  $('#conversationsInBoxMessagesWrapperDIV').html(conversationsInBoxMemberUserIDsArrayFinal);
  </code></pre>
  
  <p>I wanted to ask if there is a cleaner way to do the combining? Seems overkill to have 2 Temp Arrays like this and 3 lines of code to combine 4 arrays.</p>
  
  <p>thx</p>
