WindowProxy

A WindowProxy object is a wrapper for a Window object. A WindowProxy object exists in every {{Glossary("browsing context")}}. All operations performed on a WindowProxy object will also be applied to the underlying Window object it currently wraps. Therefore, interacting with a WindowProxy object is almost identical to directly interacting with a Window object. When a browsing context is navigated, the Window object its WindowProxy wraps is changed.
