DOMTokenList extension type

The DOMTokenList interface represents a set of space-separated tokens. Such a set is returned by Element.classList or HTMLLinkElement.relList, and many others.

A DOMTokenList is indexed beginning with 0 as with JavaScript Array objects. DOMTokenList is always case-sensitive.
