The name property represents a name for the type of error. The initial value is "Error".

Description

By default, Error instances are given the name "Error". The name property, in addition to the message property, is used by the Error.prototype.toString() method to create a string representation of the error.

Examples

Throwing a custom error

var e = new Error('Malformed input'); // e.name is 'Error'

e.name = 'ParseError';
throw e;
// e.toString() would return 'ParseError: Malformed input'
