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.
