5. 8. 13. Casting type to string

When casting type to string, JavaScript simply calls the toString() method.

The type cast can produce a string for a null or undefined value without error.


var s1 = String(null);    //"null"

var oNull = null;

var s2 = oNull.toString(); //won't work, causes an error
