Booleans

A Boolean object is a data type that can have one of two values, either true or false, used for logical operations.

To create a Boolean object, you can use the constructor or the global function, or assign a literal value. It doesn't matter which technique you use; in ActionScript 3.0, all three techniques are equivalent. (This is different from JavaScript, where a Boolean object is distinct from the Boolean primitive type.)

The following lines of code are then equivalent:
var flag:Boolean = true;
var flag:Boolean = new Boolean(true);
var flag:Boolean = Boolean(true);

Boolean methods

Boolean (expression: Object = false)
Creates a Boolean object with the specified value. If you omit the expression parameter, the Boolean object is initialized with a value of false. If you specify a value for the expression parameter, the method evaluates it and returns the result as a Boolean value according to the rules in the global Boolean() function.

toString ()
Returns the string representation ("true" or "false") of the Boolean object.

valueOf ()
Returns true if the value of the specified Boolean object is true; false otherwise

Examples

var	myStringArray	:	Array	=	new Array ("yes","could be")	;

var	name	:	data type	=	make new	;

var	myBool	:	Boolean	=	0	;

var	name	:	data type	=	init value	;

myBool	.	toString ()	;

name	.		;

myStringArray	.	push	(myBool)	;

name	.			;

trace	(myStringArray)	;	// yes, could be, false

trace	.	;	content

var	myBool2	:	Boolean	=	new Boolean ()	;

var	name	:	data type	=	make new	;

trace	(myBool2.valueOf () )	;	// false

trace		;	return

myBool	=	( 6 == 3+3 )	;

	=	numeric oper	;

trace	(myBool2.valueOf () )	;	// true

trace		;	return
