Example
The following example creates a string with all uppercase characters and then creates a copy of
that string using toLowerCase() to convert all uppercase characters to lowercase characters:
var upperCase:String = "LOREM IPSUM DOLOR";
var lowerCase:String = upperCase.toLowerCase();
trace("upperCase: " + upperCase); // output: upperCase: LOREM IPSUM DOLOR
trace("lowerCase: " + lowerCase); // output: lowerCase: lorem ipsum dolor
