Question

Does anyone know if structuring javascript will be changed? What I mean is to have a way to manage javascript classes into packages, like in Java. Is there already a way?

Answer 1

There are no JavaScript classes. There are only Objects. You can pack a bunch of objects into a different object, and treat it like a module/namespace if you wish. (example at the end.)

Because of that, there can’t be any “improvements” in the field of JavaScript classes because there aren’t any, and I hope there won’t ever be either. And frankly, that’s for the best. Would you rather deal with insane getters/setters, static members, protected, type coercion and so on etc? Prototypal inheritance beats “Classical inheritance” by miles. It’s just that JavaScript didn’t have too much time to get it just right.

For amazing explanations on how JavaScript objects work, I recommend Douglas Crockfords’ “On JavaScript”, or some answers from our very own members.

An example of “namespacing”:

var obj = {

    classRoom : {...},
    objectify : function() {...},
    capacity : 5
};
var myClass = obj.classRoom; //access it like you access a module
var capacity = 7; //this is a global variable named capacity, so it won't tamper with obj.capacity
