JavaScript Error name Property
Example
Return the error name (we have written "alert" as "adddlert" to deliberately produce an error):
try {
adddlert("Welcome guest!");
}
catch(err) {
document.getElementById("demo").innerHTML = err.name;
}

The name property sets or returns the name of an error.
Six different values can be returned by the error name property:
