This documentation is designed for people familiar with JavaScript programming and object-oriented programming concepts. There are many JavaScript tutorials available on the Web.
Introduction
The Google Hosted Libraries provides your applications with stable, reliable, high-speed, globally available access to all of the most popular, open-source JavaScript libraries.
Libraries
To load a hosted library, copy and paste the HTML snippet for that library (shown below) in your web page. For instance, to load jQuery, embed the<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script> snippet in your web page.

Troubleshooting
If you encounter problems:
- Look for typos. Remember that JavaScript is a case-sensitive language.
- Use a JavaScript debugger. Google Chrome has a full set of developer tools. In Firefox, you can use the JavaScript console or the Firebug. In IE, you can use the Microsoft Script Debugger.
- Search the discussion group. If you can't find a post that answers your question, post your question to the group along with a link to a web page that demonstrates the problem.
