Error Object
The Error object provides error information when an error occurs.
Example
In this example we have written "alert" as "adddlert" to
deliberately produce an error.
Return the error name and a description of the
error:
try
adddlert("Welcome");
catch(err)
document.getElementById("demo").innerHTML =
err.name + "<br>" + err.message;
