Part III: Appendixes > Differences from ECMA-262 and JavaScript

Appendix D. Differences from ECMA-262 and JavaScript

Naturally, this book focuses on the intricacies of ActionScript, but if you own O'Reilly's well-known JavaScript: The Definitive Guide, you'll notice that the reference section of the two books share many similarities.

Although ActionScript, like JavaScript, is based on the ECMA-262 standard, certain differences were necessitated by the constraints of Player size and backward compatibility. If you're porting code from JavaScript, JScript, or another ECMA-262-based language, you'll find Table D-1 valuable. It summarizes the intentional differences between ECMA-262, JavaScript, and ActionScript (for Flash 5 and later). Likewise, if you're porting ActionScript to another language, you'll be better able to avoid the pitfalls caused by ActionScript's deviation from the ECMA-262 standard.
