title: How does Scala's equals method work in the case of a List?
body: <pre><code>list1 == list2
  </code></pre>
  
  <p>To do the above check, will Scala iterate through both lists and call equals on each pair of elements ?</p>
  
  <p>(I am sure, this question has been asked before, but I could not find a good answer with Google &amp; Co)</p>
