Advice about OOP in JS

Actually, about long post on the techniques

Paul, could you please explain actual situation with OOP in JS? I mean, now I use…


var Foo = function()
{; // quasi extension or misc

    var me = this; // for closures and private methods

    // method overriding
    var oldConstruct = this.construct;
    this.construct = function()

        // something new

    var _p = 1; // private property

    this.getP = function() {return _p;} // public method

    var f = function()
        // private method

or singleton…

var singleton = new function()
    // something

What about interfaces, protected methods, constants and so on?.. I don’t know.

I disagree with that.

Thank’s a lot for the article. But if this the class realisation in JS, I better stay on “function as class”. At least. there I have a private properties.
