title: How to use V8's built in functions
body: <p>I'm new in both javascript and V8. According to Google's Embedder's Guide, I saw something in the <a href="http://code.google.com/apis/v8/embed.html#contexts" rel="nofollow noreferrer">context section</a> talking about built-in utility javascript functions. And I also found some .js files(e.g. math.js) in the downloaded source code, so I tried to write a simple program to call functions in these files, but I failed.</p>
  
  <ol>
  <li><p>Does a context created by <code>Persistent&lt;Context&gt; context = Context::New()</code> have any built-in js functions? How can I access them?</p></li>
  <li><p>Is there a way to first import existing js files as a library(something like src="xxx" type="text/javascript" in HTML page) and then run my own execute script?</p></li>
  <li><p>Can I call google maps api through the embedded V8 library in app? How? </p></li>
  </ol>
