JavaScript - Private/Static Property Example

gistfile1.js

function Class() {
}
Class.prototype = new function() {
	var value = 100;

	function getValue() {
		return value++;
	}

	this.getValue = getValue;
}

var a = new Class();
var b = new Class();
var c = new Class();

console.log( a.getValue() ); // 100
console.log( b.getValue() ); // 101
console.log( c.getValue() ); // 102

I agree that inheritance would be a problem in this situation, but it's just a little example. JavaScript prototype inheritance is a nasty thing to work with anyway, I avoid it whenever possible :)
