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