title: What does the .end() function do in jQuery?
body: <p>I have already read this web page <a href="http://api.jquery.com/end/" rel="noreferrer">http://api.jquery.com/end/</a> but I am still clueless on what .end() actually does. What is it for and how do you use it?</p>
  
  <p>I am also reading a jQuery book but it lightly glazes over .end() and does not give any examples of what it's for. Can someone clarify?</p>
