How do I make a playlist start playing another track when one track ends?

Question

JavaScript

There is a playlist consisting of audio elements, I create a collection of them, assign an eventListener by iteration:

var audios = document.getElementsByTagName('audio'), i = 0, len = audios.length;
for (; i < len; i++) {
  audios[i].addEventListener('ended', function() {
    audios[i + 1].playing();
  });
}

but this code doesn't work, no event handler is added. What could be wrong here? Or should the task be handled in some other way?
Judging by the console, a collection of audio elements is created, as expected, but without event handlers.

Answer 1

for (; i < len; i++)
You have before ; it must be declared from which number i to start the loop.
