Returns the current global scope object, for a normal web page this will be the current
window, for a Web Worker this will be current worker global scope via "self". The internal
implementation returns the first available instance object in the following order
globalThis (New standard)
self (Will return the current window instance for supported browsers)
window (fallback for older browser implementations)
global (NodeJS standard)
(When all else fails)
While the return type is a Window for the normal case, not all environments will support all
of the properties or functions. And this caches the lookup of the global as in some environments
this can be an expensive operation.
Parameters
OptionaluseCached: boolean
[Optional] used for testing to bypass the cached lookup, when true this will
cause the cached global to be reset.
