title: How to 'minify' Javascript code
body: <p><a href="http://jquery.com/" rel="noreferrer">JQuery</a> has two versions for download, one is <i>Production (19KB, Minified and Gzipped)</i>, and the other is <em>Development (120KB, Uncompressed Code)</em>.</p>
  
  <p>Now the compact 19kb version, if you download it, you will see is still a javascript executable code. How did they compactify it? And how can I 'minify' my code like that too?</p>
