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 for these two arrays.
false
Although the arrays appear equal, comparison by reference requires that they both refer to the
same array. The second example creates the variable, which points to the same array
thirdArray
as the variable . The equality operator will return for these two arrays because
firstArray true
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
