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


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.


Throwing a custom error

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