Browsing context
A browsing context is the environment in which a browser displays a Document
. In modern browsers, it usually is a tab, but can be a window or even only parts of a page, like a frame or an iframe.
Each browsing context has a specific origin, the origin of the active document and a history that memorize all the displayed documents, in order.
Communication between browsing context is severely constrained. Between browsing context of the same origin, a BroadcastChannel
can be opened and used.
