Sorry, I somewhat misread your message. So: The DOMTokenList array-like interface has a `toggle` method, and some others like `add`, `remove`, etc. https://developer.mozilla.org/en-US/docs/Web/API/DOMTokenList <https://developer.mozilla.org/en-US/docs/Web/API/DOMTokenList> Although, as I said, in such situations, I tend to use a Set instead of an Array. Maybe it would make sense to add a `toggle` method to `Set.prototype`? —Claude
