Page History

A table showing how each ActionScript language 'feature' is should be translated to Google Closure Tools assisted JavaScript by the FalconJS Compiler.

Using these AS3 references:

- Global Constants, Functions and Classes

- Operators

- Statements, Keywords and Directives

Using Google Closure annotations:

- Annotating JavaScript for the Closure Compiler

Table quick navigation:

- coming soon ;-)
