description: >
If "ownKeys" trap is null or undefined, [[OwnPropertyKeys]] call is
properly forwarded to [[ProxyTarget]] (which is also a Proxy object).
info: |
[[OwnPropertyKeys]] ( )
[...]
4. Let target be O.[[ProxyTarget]].
5. Let trap be ? GetMethod(handler, "ownKeys").
6. If trap is undefined, then
a. Return ? target.[[OwnPropertyKeys]]().
[[OwnPropertyKeys]] ( )
1. Let keys be a new empty List.
[...]
5. For each integer i starting with 0 such that i < len, in ascending order, do
a. Add ! ToString(i) as the last element of keys.
[...]
7. For each own property key P of O such that Type(P) is String and P is not an
array index, in ascending chronological order of property creation, do
a. Add P as the last element of keys.
8. For each own property key P of O such that Type(P) is Symbol, in ascending
chronological order of property creation, do
a. Add P as the last element of keys.
9. Return keys.
