# Interface DOMStringList

public interface DOMStringList
The `DOMStringList` interface provides the abstraction of an ordered collection of `DOMString` values, without defining or constraining how this collection is implemented. The items in the `DOMStringList` are accessible via an integral index, starting from 0.

See also the Document Object Model (DOM) Level 3 Core Specification.
