if (my_array[0] == undefined) { // No quotation marks around undefined.
trace("undefined is a special value, not a string");
} // Traces: undefined is a special value, not a string.
Usage 3: The following example creates the new Array object go_gos_array with an initial
length of 5:
var go_gos_array:Array = new Array("Belinda", "Gina", "Kathy", "Charlotte",
"Jane");
trace(go_gos_array.length); // Returns 5.
trace(go_gos_array.join(", ")); // Displays elements.
The initial elements of the go_gos_array array are identified, as shown in the following
example:
go_gos_array[0] = "Belinda";
go_gos_array[1] = "Gina";
go_gos_array[2] = "Kathy";
go_gos_array[3] = "Charlotte";
go_gos_array[4] = "Jane";
The following code adds a sixth element to the go_gos_array array and changes the second
element:
go_gos_array[5] = "Donna";
go_gos_array[1] = "Nina"
trace(go_gos_array.join(" + "));
// Returns Belinda + Nina + Kathy + Charlotte + Jane + Donna.
