How can I make my object acts like an array (but not only) ?

Question

Imagine I create a class Rect which has one attribute : this.rect (an array [x, y, w, h]). And some get / set attributes : this.top returns this.rect[y].

How can I do this :
r = new Rect (1, 2, 3, 4);
console.log(r) => [1, 2, 3, 4]
console.log(r[0]) => 1
console.log(r.top) => 2

Hope you understood (I am french). Thank.
