Recently, I created a tampermokey script that keeps track of the i intervals and automatically clicks on the next video. However, it's quite strange that the script only works properly when the alert line is uncommented:
var i = 1;
setInterval(function () {
document.getElementsByClassName('PlaylistVideo')[i].click();
// alert("i is equal to: "+ i);
i ++
}, 5000);
When working with Javascript arrays, it's important to remember that they are zero-based, meaning you should always begin your index count at 0.
let index = 0;
It seems that the \ alert wasn't well received for some unknown reason.
