THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

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
- Statements, Keywords and Directives
Using Google Closure annotations:
- Annotating JavaScript for the Closure Compiler
Table quick navigation:
- coming soon ;-)
Legend for Javascript column color usage:
Black: JavaScript matches ActionScript
Red: solution not agreed upon
Blue: solution looks good, need consencus to approve (use Comments or Notes column)
Green: solution agreed upon

There is no matching method in Javascript. Do we use a utility method that returns an array, or do we just use a 'new' Array object?

There is no matching implementation in JavaScript. We may need to build a utility function to cover this one.

Object()
...
-
...
result = Object(value) ;
...
Wiki Markup result = /*\* @type {Object} \*/ value;
...
In ActionScript, calling 'Object(value)' returns 'value' (since all values are objects). Given that, does it make sense to just write 'value' in JavaScript and let the Closure Compiler "cast" it?

We may need a utility function to wrap 'console.log', as not all browsers have debugging enable, and calling to a non-existent 'console' object will cause an error.

...
Let the Closure Compiler handle (check) what is basically a type cast from general Array to a Typed Array.
