[] array access operator

myArray = [ a0, a1,...aN ]
myArray[ i ] = value
myObject [ propertyName ]
Initializes a new array or multidimensional array with the specified elements ( , and so on),
a0
or accesses elements in an array. The array access operator lets you dynamically set and retrieve
instance, variable, and object names. It also lets you access object properties.
Usage 1: An array is an object whose properties are called elements, which are each identified
by a number called an index. When you create an array, you surround the elements with the
array access ([]) operator (or brackets). An array can contain elements of various types. For
example, the following array, called , has three elements; the first is a number and
employee
the second two are strings (inside quotation marks):
var employee:Array = [15, "Barbara", "Jay"];
You can nest brackets to simulate multidimensional arrays. You can nest arrays up to 256
levels deep. The following code creates an array called with three elements; each
ticTacToe
element is also an array with three elements:
var ticTacToe:Array = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]; // Select Debug >
List Variables in test mode
// to see a list of the array elements.
