message property is a human-readable description of the error.
This property contains a brief description of the error if one is available or has been set. SpiderMonkey makes extensive use of the
message property for exceptions. 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
var e = new Error('Could not parse input'); // e.message is 'Could not parse input' throw e;
