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'
