title: Is it needed to close the <script> tag when it's used for embedding an external script file?
body: <p>In old times we used to embed external JavaScript this way:</p>
  
  <pre><code>&lt;script src="external.js" type="text/javascript"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>HTML5 came to save our eyes and fingers, so the construct became shorter:</p>
  
  <pre><code>&lt;script src=external.js&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Not a big deal, I'm just curious if we can leave away the enclosing <code>&lt;/script&gt;</code>?</p>
  
  <p>Like this:</p>
  
  <pre><code>/* This code may fail */
  
  &lt;script src=external.js/&gt;
  </code></pre>
