For whatever reason the browser gods have decreed `alert()` has priority is the callstack. So if in your `for loop` you put a `console.log(i)` above the `alert()` you will see `0 1 2` logged but not `3` (fourth iteration) and you will still see a fourth `alert()` (which is now `undefined`) Somehow the alert can jump the gun before your `for loop` evaluates the `i < Target.length` and jump the que in front of any code in the loop block. I once built a `mutationObserver` that would see if any `script` had been injected into the `DOM` and immediately remove the `script` before executing. It worked fine and would kill the script before any code could run… except `alert()`. It was the only code that would jump the que and evaluate… Alert also blocks any JS running until it has been clicked. ---
