About arrays

An array is an object whose properties are identified by numbers representing their positions
in the structure. Essentially, an array is a list of items. It's important to remember that each
element in an array doesn't have to be the same data type. You can mix numbers, dates,
strings, and objects and even add a nested array at each array index.
The following example is a simple array of month names.
var myArr:Array = new Array();
myArr[0] = "January";
myArr[1] = "February";
myArr[2] = "March";
myArr[3] = "April";
The previous array of month names can also be rewritten as follows:
var myArr:Array = new Array("January", "February", "March", "April");
Or, you can use shorthand syntax, as follows:
var myArr:Array = ["January", "February", "March", "April"];
An array is like a structure for data. An array is like an office building, where each floor
contains a different piece of data (such as accounting on floor 3, and engineering on floor 5). As
such, you can store different kinds of data in a single array, including other arrays. Each floor
of this building can contain multiple kinds of content (executives and accounting might share
floor 3).
An array contains elements, which are equivalent to each floor of the building. Each element
has a numeric position (the index), which is how you refer to each element's position in the
array. This is similar to how each floor in a building has a floor number. Each element can
either hold a piece of data (which could be a number, string, Boolean value, or even an array
or object) or be empty.
You can also control and modify the array itself. For example, you might want to move the
engineering department to the basement of the building. Arrays let you move values around,
and they let you change the size of the array (say, renovate the building and add more floors or
remove floors). As such, you can add or remove elements and move values to different
elements.
Therefore, the building (the array) contains floors (the elements), which are numbered floors
(the index), and each floor contains one or more departments (the values).
