[edit] Summary

[edit] 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.

[edit] Examples

[edit] Example: Throwing a custom error

var e = new Error("Malformed input"); // e.name is "Error"
e.name = "ParseError";                // e.toString() would return
throw e;                              // "ParseError: Malformed input"
