Recursive function stopping for no reason-CodePudding

I have a recursive function reopen() which is supposed to loop indefinitely however after calling the function openWin() it stops for some reason.

Here is the code:

function openWin(i = 0) {
  win[i] = window.open(url,'', 'width=200,height=200');
  wins  ;
}

function reopen() {
  for(var i = 0; i < wins; i  ) {
    if(win[i].closed) {
        openWin(i);
        openWin(wins);
    }
  }
  setTimeout(reopen, 10);
}

Any idea why this is happening and how to fix it?

EDIT: A lot of people seem to think that the problem is coming from calling openWin() twice, however it has the exact same problem when only calling it once

You have an infinite loop. Each time you call openWin() it inrements wins. Since you call openWin() twice in the loop when win[i] isn't open, you'll add 2 to wins during some of the repetitions of the loop. So i < wins will always be true, because wins increases faster than i does.

function reopen() {
  const wincount = wins;
  for(var i = 0; i < wincount; i  ) {
    if(win[i].closed) {
        openWin(i);
        openWin(wins);
    }
  }
  setTimeout(reopen, 10);
}

For some reason the loop was having problems with calling a function, but by copying the code from openWin() and pasting it in directly it works now :)
