The string object can be explicitly created with string literals.
A string object created in this way (referring to a standard string) differs from the processing of a string object created with the new operator.
All string literals share a common global string object. If you add a property to a string literal, it is available to all standard string objects:
*/
var str3 = "Hello";
alert (STR3);//hello
