If "get" trap is null or undefined, [[Get]] call is properly
|
|
forwarded to [[ProxyTarget]] (which is also a Proxy object).
|

info: |
|

[[Get]] ( P, Receiver )
|
|
|
|
[...]
|
|
5. Let target be O.[[ProxyTarget]].
|
|
6. Let trap be ? GetMethod(handler, "get").
|
|
7. If trap is undefined, then
