When you have a DOM element reference you can remove a class using the remove
method:
element.classList.remove('myclass')
You can add a new class to it by using the add
method:
element.classList.add('myclass')
Implementation detail: classList
is not an array, but rather it is a collection of type DOMTokenList.
You canโt directly edit classList
because itโs a read-only property. You can however use its methods to change the element classes.
