  2. Let keys be target.[[OwnPropertyKeys]]().
  3. ReturnIfAbrupt(keys).
  4. Return CreateArrayFromList(keys).

  1. Let keys be a new empty List.
  2. For each own property key P of O that is an array index, in ascending
  numeric index order
    a. Add P as the last element of keys.
  3. For each own property key P of O that is a String but is not an array
  index, in property creation order
    a. Add P as the last element of keys.
  4. For each own property key P of O that is a Symbol, in property creation
  order
    a. Add P as the last element of keys.
  5. Return keys.
