How to implement inheritance in Node.JS

Question

How do we use 'inheritance' in Node.JS? I heard that prototype is similar to interfaces in java. But I have no idea how to use it!

Answer 1

Although there are various ways of performing inheritance and OO in javascript, in Node.js you would typically use the built in util.inherits function to create a constructor which inherits from another.

See http://book.mixu.net/ch6.html for a good discussion on this subject.

for example:

var util = require("util");
var events = require("events");

function MyOwnClass() {
    // ... your code.
}

util.inherits(MyOwnClass, events.EventEmitter);
