title: Why do we have newlines in minified JavaScript?
body: <p>I know about a <a href="https://stackoverflow.com/questions/3118776/when-i-minify-css-or-js-why-isnt-it-all-on-one-line">similar question</a> but it is a <em>tiny</em> bit off from what I am asking here, so <em>please</em> don't <code>flag</code> it as a duplicate.</p>
  
  <p>When you see the <a href="http://code.jquery.com/jquery-1.7.2.min.js" rel="noreferrer">production version of jQuery</a>, why is there a newline after a while? I downloaded a copy and deleted all the newlines (apart from the licence) and it still worked. (I ran the <strong>entire</strong> unit test suite against my changes on Mozilla Firefox, Google Chrome and Opera.)</p>

  <p>I know three newlines (not counting the license) is not going to slow it down a lot, but still, doesn't every tiny bit help?</p>
  
  <p>I have assigned myself a small challenge, to squeeze every little bit of performance out of my JavaScript code.</p>
