The Different Types of Exceptions

In JavaScript, you can throw any type of object. However, thrown objects may possess different characteristics. Although it is usual to throw strings and/or numbers as error messages, it is usually more beneficial to utilize the exception types designed for this purpose.

DOMError – This exception represents a named error object.

DOMException - This exception indicates an abnormal situation that happens while a property or method is being used. To use this exception, you must add DOMError() into your code.
