title: Which one is faster between map, collect, select and pluck?
body: <p>I have been using different methods to get specific fields from active record, But which one is faster and preferred to use and how are they different from one another?</p>
  
  <pre><code>User.all.collect(&amp;:name)
  User.all.pluck(:name)
  User.all.select(:name)
  User.all.map(&amp;:name)
  </code></pre>
  
  <p>Thanks for your help in advance.</p>
