The DOMString interface is a legacy type returned by some APIs and represents a non-modifiable list of strings (DOMString). Modern APIs use Array objects (in WebIDL: sequence<DOMString>) instead.
This interface is used in IndexedDB and in the Location API:
DOMStringList.length Read only
Returns the size of the list.
DOMStringList.item()Returns a string from the list with the given index.
DOMStringList.contains()Returns a boolean indicating whether the given string is in the list.
