Question

I’ve found http://ejohn.org/blog/simple-javascript-inheritance/ and it’s exactly what I’m searching for but ‘m wondering if it still works and if can cause any issue.

Answer 1

Many modern libraries use classical inheritance now. Its core method is the following (JavaScript Patterns by Stoyan Stefanov, page 127):

function inherit(C, P) { 
    var F = function () {}; 
    F.prototype = P.prototype; 
    C.prototype = new F(); 
    C.uber = P.prototype; 
    C.prototype.constructor = C; 
} 

Example of projects where it’s used are:

• Google Closure
• YUI
• ExtJS
