Error.prototype.message

The message property is a human-readable description of the error.

Description

This property contains a brief description of the error if one is available or has been set. The message property combined with the name property is used by the Error.prototype.toString() method to create a string representation of the Error.

By default, the message property is an empty string, but this behavior can be overridden for an instance by specifying a message as the first argument to the Error constructor.

Examples

Throwing a custom error

const e = new Error('Could not parse input');
// e.message is 'Could not parse input'
throw e;
