Syncronous (safe) setInterval()

syncInterval.js

// Syncronous setInterval
// Usage:
//     var interval = new SyncInterval(function () {
//         console.log('bob');
//     }, 500);
//     interval.stop();
// Written by Luke Morton, Richard Willis
function SyncInterval(fn, wait, scope) {
	var t = this;
	wait = wait || 1000;

	t.timeout = setTimeout(function () {
		fn.call(scope);
		t.timeout = setTimeout(arguments.callee, wait);
	}, wait);
}

SyncInterval.prototype.stop = function () {
	clearTimeout(this.timeout);
};

Aye very cool :)

Hey @drpheltright, it might be worth reverting the arguments.callee call, and instead naming the function. (It appears arguments.callee is deprecated and won't work in strict mode, see http://ejohn.org/blog/ecmascript-5-strict-mode-json-and-more/)

t.timeout = setTimeout(function timer() {
    fn.call(scope);
    t.timeout = setTimeout(timer, wait);
}, wait);
