var timer1 = (cb, time) => {
(function loop() {
cb();
setTimeout(loop, time);
})();
};
var timer2 = (cb, time) => {
cb();
setInterval(cb, time);
}; Recursive, indirect.
the difference is that 1 stops when cb throws an exception and 2 doesn't stop.
another difference is that 1 can be transformed into high precision, while 2 depends entirely on the accuracy of the browser itself
timer1 and timer2 is actually the difference between setTimeout and setInterval setTimeout()
