Fails on JSAPI failure.
Get the expando object, or null if there is none.
If
proxy (underneath any functionally-transparent wrapper proxies) has as
its [[GetPrototypeOf]] trap the ordinary [[GetPrototypeOf]] behavior
defined for ordinary objects, set *is_ordinary to true and store obj’s
prototype in proto. Otherwise set *isOrdinary to false. In case of
error, both outparams have unspecified value.id_to_source 🔒 ⚠

Initialize the infrastructure for DOM proxy objects.
Reports whether the object is Extensible

[[Set]] for Location.Controls whether the Extensible bit can be changed
Report a cross-origin denial for a property, Always returns
false, so it
can be used as return report_cross_origin_denial(...);.Set the property descriptor’s object to
obj and set it to enumerable,
and writable if readonly is true.Determine if this id shadows any existing properties for this proxy.
