custom-error-node-js.js

"use strict";


var util = require("util");


var errors = {};

errors.ErrorA = function ErrorA(message) {

	Error.call(this);
	Error.captureStackTrace(this, this.constructor);
	this.name = errors.ErrorA.name;
	this.message = message;
};


util.inherits(errors.ErrorA, Error);

	
try {
	throw new errors.ErrorA("My Error A!");
} catch(err) {
	console.log("Name: " + err.name);
	console.log("Message: " + err.message);
	console.log("Stack: " + err.stack);
}
