JAVASCRIPT
Arcane Ages contains an embedded JavaScript compiler and interpreter and uses JavaScript as a way of allowing builders to add more interactive and intelligent behavior to their creations.
If you would like to get a book on JavaScript, I highly recommend JavaScript: The Definitive Guide, 4nd Edition, by David Flanagan, O'Reilly and Associates. This book separates Core JavaScript from browser-specific parts of it. The first half of the book is directly applicable to use of JavaScript on Arcane Ages. There are also a lot of free information on JavaScript on the Internet.
