The following example illustrates comparison by reference with two arrays:
var a:Array = [ 1, 2, 3 ];
var b:Array = [ 1, 2, 3 ];
trace(a); // 1, 2, 3
trace(b); // 1, 2, 3
trace(a!=b); // true
a = b;
trace(a); // 1, 2, 3
trace(b); // 1, 2, 3
trace(a!=b); // false
// trace statement output:
1,2,3
1,2,3
true
1,2,3
1,2,3
false
