About using operators with strings
Comparison operators compare strings only if both operands are strings. An exception to this
rule is the strict equality (
===) operator. If only one operand is a string, ActionScript converts
both operands to numbers and performs a numeric comparison on them. For more
information on numeric operators, see “Using numeric operators” on page 188.
Except for the equality operator (
==), comparison operators (>, >=, <, and <=) affect strings
differently than when they operate on other values.
Comparison operators compare strings to determine which is first alphabetically. Strings with
uppercase characters precede strings that are lowercase. That means that "Egg" comes before
"chicken".
var c:String = "chicken";
var e:String = "Egg";
trace(c < e); // false
var riddleArr:Array = new Array(c, e);
trace(riddleArr); // chicken,Egg
trace(riddleArr.sort()); // Egg,chicken
