title: Is Laravel's 'pluck' method cheaper than a general 'get'?
body: <p>I'm trying to dramatically cut down on pricey DB queries for an app I'm building, and thought I should perhaps just return IDs of a child collection (then find the related object from my React state), rather than returning the children themselves. </p>
  
  <p>I suppose I'm asking, if I use <em>'pluck'</em> to just return child IDs, is that more efficient than a general <em>'get'</em>, or would I be wasting my time with that?</p>
