I recently came across an explanation on how to properly use the setInterval() function. Essentially, it was mentioned that
(function(){
// perform some actions
setTimeout(arguments.callee, 60000);
})();
ensures that the subsequent call from setTimeout is not initiated until the current one has completed. What is the reason behind this behavior when using self-invoking functions?
Utilizing an immediately-invoked function expression doesn't automatically trigger the desired behavior; in fact, employing setTimeout() as opposed to setInterval() is the key factor here. The way setInterval() operates means that it won't begin the next cycle until the current one has finished (unless there's an asynchronous operation involved). On the other hand, opting for setTimeout provides more flexibility in controlling the time intervals between iterations.
Addtionally, it's advisable not to structure the code like this. Rather, try:
(function loop() {
// code
setTimeout(loop, 60000);
})();
Resorting to using arguments.callee should be avoided unless absolutely necessary.
