I would like to learn if it is possible to redefine the "definePropery" function of the Object(.prototype) in a subclass(.prototype) so that the setter not only sets the value of the property but also eg executes an additional method.

I have tried something like that:

Myclass.prototype.defineProperty = function (obj, prop, meth) {
    Object.defineProperty.call(this, obj, prop, {
        get: function () {
            return obj[prop]
        },
        set: function () {
            obj[prop] = n;
            alert("dev")
        }
    })
}

But id does not work
