The flash.error package contains error classes that are part of the Flash Player Application Programming Interface (API), rather than part of the ActionScript core language.

The ActionScript core language is the part of the language that complies with the ECMAScript standard. The Flash Player API is the part of the language that is specific to ActionScript. The flash.error package relates to Flash Player specific functionality (Flash Player API).

The error classes that are not part of the flash.error package are top level core classes that are based on the ECMAScript standard.

Note: In ActionScript 3.0, exceptions are the primary mechanism for reporting runtime errors. Error events are a secondary mechanism that are used when errors are encountered during an asynchronous operation, such as a call to the Loader.load() method.
