class Observed {
    constructor(onChange) {
        this._onChange = onChange;
    }

    get value() {
        return this._val;
    }

    set value(val) {
        if (this._val !== val) {
            this._val = val;
            this._onChange(this._val);
        }
    }
}

var obs = new Observed(async val => {
    element.setAttribute("visibility", "hidden");
});
obs.value = 5;

var val = 5;
