24.76. Error.name: the type of an error

ECMAScript v3

24.76.1. Synopsis

error.name

24.76.2. Description

The name property of an Error object (or of an instance of any subclass of Error) specifies the type of error or exception that occurred. All Error objects inherit this property from their constructor. The value of the property is the same as the name of the constructor. Thus SyntaxError objects have a name property of "SyntaxError", and EvalError objects have a name of "EvalError".
