title: What is a JavaScript pre-compiled library?
body: <p>I'm learning how to use <a href="http://en.wikipedia.org/wiki/Magento" rel="nofollow noreferrer">Magento</a> e-commerce system, and I'm reading its documentation, but I don't understand some term, a "pre-compiled JavaScript library". What do they mean by that? How can JavaScript code be compiled?</p>
  
  <blockquote>
    <p>The web downloader for upgrading and installing Magento without the
    use of SSH (covered in Chapter 2). • js—The core folder where all
    JavaScript code included with the installation of Magento is kept. We
    will find all pre-compiled libraries of JavaScript here.</p>
