❮ JavaScript Error Reference

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;
}
Try it Yourself »

Definition and Usage

The name property sets or returns the name of an error.

Six different values can be returned by the error name property:
