I am trying to access DOM Element class name .menu-item i am not able to access them. Please help me why i am not able to access them. I have checked by alert() that js is working and in console.log the lengh of menu-items is 0. Please help in resolving this issue. I am learning this from youtube video.
const menuItems = document.querySelectorAll('.menu-item');
console.log(menuItems.length);
menuItems.forEach(item => {
item.addEventListener("click",() => {
item.classList.add('active');
})
})<!DOCTYPE html>
