SetTimeout for XHR Requests

Question

quoting MDC :

If it is likely that your logic may take longer than the interval time, it is recommended that you call the named function recursively using window.setTimeout. For example, when using setInterval to poll a remote server every 5 seconds, network latency, a non-responding server, and many other problems can prevent the request from completing at its appointed time. That way, you might end up in a queue with XHR requests that don't necessarily return in order.

For such cases, the recursive setTimeout pattern is preferred:

(function loop(){
   setTimeout(function(){

      // logic here

      // recurse
      loop();

  }, 1000);
})();
