JavaScript Error Reference

Error Object

The Error object provides error information when an error occurs.

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;
}
