Question

Is there anything like a “dispose” function or “thread shutdown hook” for a specific thread running via setInterval?

Answer 1

(function () {
    var _setInterval = window.setInterval,
        _clearInterval = window.clearInterval;



    window.setInterval = function (fn, time) {
        //Implement your hooks here, hopefully without side effects
        return _setInterval(fn, time);
    };

    window.clearInterval = function (id) {
        //Implement your hooks here, hopefully without side effects
        return _clearInterval(id);
    };

})()

From comments it became clear that you don’t need hooking because you are in an environment that you control. In that case you can just write wrapper functions like myClearInterval etc. with same principle.
