FLASH® LITE™ 2.x - Adobe Help and Support

Example
var myArray:Array = Array();
myArray.push(12);
trace(myArray); //traces 12
myArray[4] = 7;
trace(myArray); //traces 12,undefined,undefined,undefined,7
Usage 2: The following example creates an array of length 4 but with no elements defined:
var myArray:Array = Array(4);
trace(myArray.length); // traces 4
trace(myArray); // traces undefined,undefined,undefined,undefined
Usage 3: The following example creates an array with three defined elements:
var myArray:Array = Array("firstElement", "secondElement", "thirdElement");
trace (myArray); // traces firstElement,secondElement,thirdElement

Array
Unlike the Array class constructor, the Array() function does not use the keyword new .
Boolean function
Boolean(expression:Object) : Boolean
Converts the parameter expression to a Boolean value and returns a value as described in the
following list:
■ If expression is a Boolean value, the return value is expression.
■ If expression is a number, the return value is true if the number is not zero; otherwise
the return value is false.
If expression is a string, the return value is as follows:
■ In files published for Flash Player 6 or earlier, the string is first converted to a number; the
value is true if the number is not zero, false otherwise.
■ In files published for Flash Player 7 or later, the result is true if the string has a length
greater than zero; the value is false for an empty string.
If expression is a string, the result is true if the string has a length greater than zero; the
value is false for an empty string.
■ If expression is undefined or NaN (not a number), the return value is false.
