The message property is a human-readable description of the error.
Error.prototype.message
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
var e = new Error('Could not parse input'); // e.message is 'Could not parse input' throw e;
