let buttons = document.getElementsByClassName("js-download-button");
let i = 0;
let interval = setInterval(() => {
if(i > buttons.length)
{
clearInterval(interval);
}
else{
buttons[i].click();
console.log(++i)
console.log('Downloading: '+buttons[i - 1].parentNode.parentNode.parentNode.children[0].children[0].children[0].innerHTML);
}
}, 1000);

Additional quick edit, switched if/else statements, moved console.log(i++) and replaced i++ with ++i.
Console now returns the value of i before the Downloading message, and starts at 1.
