-Makes a `DELETE` request to the passed URL.

+Works for both negative and positive integers.
 
-Use `XMLHttpRequest` web api to make a `delete` request to the given `url`.
+If `divisor` is `-1` or `1` return `Infinity`.
-Handle the `onload` event, by running the provided `callback` function.
+If `divisor` is `-0` or `0` return `0`.
-Handle the `onerror` event, by running the provided `err` function.
+Otherwise, keep dividing `num` with `divisor` and incrementing `i`, while the result is an integer.
-Omit the third argument, `err` to log the request to the console's error stream by default.
+Return the number of times the loop was executed, `i`.
