<h1>SWIG and Javascript</h1>
<p>This chapter describes SWIG's support of Javascript. It does not cover SWIG basics, but only information that is specific to this module.</p>
<h2>Overview</h2>
<p>JavaScript is a prototype-based scripting language that is dynamic, weakly typed and has first-class functions. Its arguably the most popular language for web development. Beyond of being a browser-based scripting language, with <a href="http://nodejs.org">node.js</a> Javascript has found its way to a backend development language, too.</p>
<p>Native Javascript extensions can be used for applications that embed a web-browser view or that embed a Javascript engine (such as <em>node.js</em>). Extending a general purpose web-browser is not possible as this would be severe security issue.</p>
<p>SWIG Javasript currently supports <strong>JavascriptCore</strong>, the Javascript engine used by <code>Safari/Webkit</code>, and <strong>v8</strong>, which is used by <code>Chromium</code> and <code>node.js</code>.</p>
