title: JS - Difference between $("#elementid") vs document.getElementById?
body: <p>What are the differences, if any, between <code>$("#elementID")</code> vs <code>document.getElementById("elementID")</code>?<br>
  Can they both do the same things?</p>
  
  <p>What are these things called? Objects?<br>
  i.e.<br>
  if I have <code>x = $("#elementID")</code>, what is x?<br>
  if I have <code>y = document.getElementById("elementID")</code>, what is y?   </p>
