var y:String = "steve";

trace(x == y); // output: false

The following examples show comparison by reference. The first example compares two arrays

with identical length and elements. The equality operator will return

false for these two arrays.

Although the arrays appear equal, comparison by reference requires that they both refer to the

same array. The second example creates the

thirdArray variable, which points to the same array

as the variable

firstArray. The equality operator will return true for these two arrays because

the two variables refer to the same array.

var firstArray:Array = new Array("one", "two", "three");

var secondArray:Array = new Array("one", "two", "three");

trace(firstArray == secondArray); // will output false

// Arrays are only considered equal

// if the variables refer to the same array.

var thirdArray:Array = firstArray;

trace(firstArray == thirdArray); // will output true
