Javascript DOM support

Question

Does solo learn not handle querySelectorAll()

Answer 1

That is happening because you have to handle onload of window.
Sololearn by default embed JavaScript in head section, so you have to handle it first.
Like so,
window.onload = () => {
let li = document.querySelectorAll("li");
console.log(li.length);
}

Answer 2

I just checked.
Sololearn definitely handles querySelectorAll().
