Proper way of creating custom error object

[Denys Khanzhiyev]

With following code 

var 

 util = require('util');

function err1(){

    Error.call(this,arguments);   

}

err1.prorotype = Error.prototype;

function err2(){

}

err2.prorotype = Error.prototype;

function err3(){

    Error.call(this,arguments);   

}

util.inherits(err3,Error);

var

   e0 = new Error('zz'),

   e1 = new err1('z1'),

   e2 = new err2('z2'),

   e3 = new err3('z3');

console.log(e0.stack);

console.log(e1.stack);

console.log(e2.stack);

console.log(e3.stack);

Only e0.stack is defined

I want stack in my error object.
