    Error.prototype.message

    Summary

    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. 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 Error constructor.

    Examples

    Example: Throwing a custom error

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