FLASH® LITE™ 2.x - Adobe Help and Support

Because all string indexes are zero-based, the index of the last character for any string x is
x.length - 1.
You can call any of the methods of the String class using the constructor method new String
or using a string literal value. If you specify a string literal, the ActionScript interpreter
automatically converts it to a temporary String object, calls the method, and then discards the
temporary String object. You can also use the String.length property with a string literal.
Do not confuse a string literal with a String object. In the following example, the first line of
code creates the string literal first_string, and the second line of code creates the String
object second_string:
var first_string:String = "foo"
var second_string:String = new String("foo")
Use string literals unless you specifically need to use a String object.
