timer.js

function Timer(func, delay, start) {
    this.func = func;
    this.delay = delay;
    this.running = false;
    if(start) this.start();
}

Timer.prototype.start = function(delay) {
    this.running = true;
    return this.interval = setInterval(this.func, (delay || this.delay));
}

Timer.prototype.stop = function() {
    this.running = false;
    clearInterval(this.interval);
}

// timer = new Timer(function() { }, 1000); timer.start(); timer.running == true; timer.stop();
