var Pet = JSClass({
    name: function(name) {
        if (typeof name === 'undefined') {
            return this.name;
        }
        this.name = name;
    }
});
var Animal = Class({
    eat: function() {
        this.fed = true;
    },
    drink: function() {
        this.thirsty = false;
    }
});
var Dog = JSClass({
}).mixin(Pet, Animal);
var pluto = new Dog();
pluto.eat();
pluto.name('pluto');

console.log(pluto.name());//pluto
console.log(pluto.thirsty);//false

So I am a bit confused about this example (and a newbie so please forgive if the following is silly).

First, I think that 'var Animal = Class' should be var Animal =JSClass. If not, can you explain?

Second, as I understand it, a class provides methods that are inherited. So in the case of Pluto, he inherits the method eat via the mixin containing Animal. You then call the method pluto.eat() which assigns the property eat to Pluto. But you did not do that for drink. So shouldn't 'console.log(pluto.thirsty);//false' return 'undefined'?

Reading through the documentation, it seems that the super() function is only supported for ES6?

If so, it would be super handy to have that function available for ES5 -- I know I've seen other JS class libs do it.

Hi i have 2 classes A and B, B is a subclass of A.

var A = Class({});
var B = A.extend({});

If i want to test if my current object is actually of type A and not type B how would i do this without specificially checking that its not any of its subtypes:

var x = new A();
var y = new B();

x.typeOf(A); //true
x instanceof A; //true

y.typeOf(A); //true
y instanceof A; //true

So from my perspective i cant tell that x is of type A only, without starting to test for all the subclasses i dont want it to be.

in java i would do something like:

x.getClass() == A.class; //True
y.getClass() == A.class; //False (Since its class is B)

Minimal repro based on the code in the readme:

var StaticExample = JSClass({
    }).static({
        myStatic: 'myStatic',
        myStatic2: 'myStatic2'
    });
    console.log(StaticExample.myStatic);//myStatic2
    console.log(StaticExample.myStatic2);//myStatic2

Hi.
It would be so nice if we can retrieve the class object from an instance.
Like this:

var Dog = JSClass({
    ...
}).static({
    species: 'C. lupus'
});

var myPet = new Dog();
console.log( myPet.getClass().species ); // "C. lupus"

if (myPet.getClass() === Dog) { // true
    ...
}

Or can I already do the same thing somehow?

Would it be possible to register js.class with Bower?

I was able to install it using the direct gihub url:
bower install https://github.com/dkraczkowski/js.class.git#2.5.2

But I would like to simply keep it in my bower.json file and have it install by itself. (Easier when dealing with many machines).
