toggle a class using javascript

Hi I am doing a small app for practice and I want a class too be toggled to the element when its clicked. I have managed to add the class when on click event using this code : for(let i = 0; i < li.length; i += 1){ li[i].addEventListener( 'click', () => { event.target.className = 'checked'; });} However when I used .toggle or className.toggle the class fail to be added/ removed

const liElements = document.querySelectorAll('li');

liElements.forEach((li, i) => {
    li.addEventListener('click', () => li.classList.toggle('checked'));
});

Try something like this.
