AS to JS translation table

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 ;-)

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

	Test Available In FlexJS (+/-)?	ActionScript	JavaScript + Closure annotation	Notes
Global Constants
Infinity	-	Infinity	Infinity
-Infinity	-	-Infinity	-Infinity
NaN	-	NaN	NaN
undefined	-	undefined	undefined

Global Functions
Array()	-	Array(...values)	new Array(...values)	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?
Boolean()	-	Boolean(value)	new Boolean(value)	See "Array" function note.
decodeURI()	-	decodeURI(value)	decodeURI(value)
decodeURIComponent()	-	decodeURIComponent(value)	decodeURIComponent(value)
encodeURI()	-	encodeURI(value)	encodeURI(value)
encodeURIComponent()	-	encodeURIComponent(value)	encodeURIComponent(value)
escape()	-	escape(value)	escape(value)
int()	-	int(value)	(value >> 0)
isFinite()	-	isFinite(value)	isFinite(value)
isNaN()	-	isNaN(value)	isNaN(value)
isXMLName()	-	isXMLName(value)	?	There is no matching implementation in JavaScript. We may need to build a utility function to cover this one.
Number()	-	Number(value)	new Number(value)	See "Array" function note.
Object()	-	result = Object(value) ;	result = /** @type Unknown macro: {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?
parseFloat()	-	parseFloat(value)	parseFloat(value)
<ac:structured-macro ac:name="unmigrated-wiki-markup" ac:schema-version="1" ac:macro-id="c9270b46-62cd-4ca5-8404-e2d389a4a5c3"><ac:plain-text-body><![CDATA[	parseInt()	-	parseInt(value, [radix])	parseInt(value, [radix])	]]></ac:plain-text-body></ac:structured-macro>
String()	-	String(value)	new String(value)	See "Array" function note.
trace()	-	trace(...values)	console.log(...values)	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.
uint()		uint(value)	(value >>> 0)
unescape()	-	unescape(value)	unescape(value)
Vector()	-	result = Vector.<type>(valueArray);	result = /** @type Unknown macro: {Array.<type>} */ valueArray;	Let the Closure Compiler handle (check) what is basically a type cast from general Array to a Typed Array.
XML()	-	XML(value)	?	Use 'goog.dom.xml'?
XMLList()		XMLList(value)	?	Use 'goog.dom.xml'?

Classes
ArgumentError	-	ArgumentError	Error	Need utility class and cast a regular error object to that, for the sake of the Closure Compiler?
arguments	-	arguments	arguments
Array	-	Array	Array	Not sure if all properties and methods of AS Array class map to the JS Array class.
Boolean		Boolean	Boolean
Class	-	package com.example.components { public class MyClass { public function MyClass() {} } }	goog.provide('com.example.components.MyClass'); /** * @constructor */ com.example.components.MyClass = function() {};
Date	-	Date	Date	The JS class seems to be missing all the properties that the AS class offers. The methods on both classes match, AFAICT.
DefinitionError	-	DefinitionError	Error	Need utility class and cast a regular Error object to that, for the sake of the Closure Compiler?
Error	-	Error	Error	There is no 'errorID' property on the JS Error class
EvalError	-	EvalError	EvalError	Need utility class and cast a regular Error object to that, for the sake of the Closure Compiler?
Function	-	Function	Function
int	-	int	Number
JSON	-	JSON	JSON	How about support for "older" browsers? Do we provide "if not JSON, add custom JSON to window object"?
Math	-	Math	Math
Namespace	-	Namespace	?	Do we need a utility class?
Number	-	Number	Number
Object	-	Object	Object	"setPropertyIsEnumerable" not available on JS Object.prototype...
