Using this code to loop audio in a game, but it does not work. Why?

Question

I used the below code in my JS file for a sliding puzzle game, but it does not work. What am I doing wrong?

var backgroundSound= new Audio("tetris.mp3");
backgroundSound.addEventListener('ended', function() {
    this.currentTime = 0;
    this.play();
}, false);
backgroundSound.play();

Answer 1

You can use loop to do that:

backgroundSound.loop = true;
