The code examples in the book are the key to hands-on learning. Each code snippet is part of a larger, functional plugin. You can download the complete source code from the official GitHub repository for the third edition. This is invaluable for seeing the finished product or troubleshooting your own code.
To actually use the book, you need a local test server:
Use JavaScript, jQuery, and AJAX to make pages interactive, and learn to fetch data from external sources. The code examples in the book are the
