typedef js.html.MediaQueryListListenerAvailable in js
This page is not complete.

A MediaQueryList object maintains a list of media queries on a document , and handles sending notifications to listeners when the media queries on the document change.

This makes it possible to observe a document to detect when its media queries change, instead of polling the values periodically, if you need to programmatically detect changes to the values of media queries on a document.

Documentation for this class was provided by MDN.
