  1. Let promise be the this value.
  2. Return ? Invoke(promise, "then", «undefined, onRejected»).

  7.3.18 Invoke

  1. Assert: IsPropertyKey(P) is true.
  2. If argumentsList was not passed, let argumentsList be a new empty List.
  3. Let func be ? GetV(V, P).
  4. Return ? Call(func, V, argumentsList).

  7.3.2 GetV

  1. Assert: IsPropertyKey(P) is true.
  2. Let O be ? ToObject(V).
  3. Return ? O.[[Get]](P, V).

  7.3.12 Call (F, V [ , argumentsList ])

  1. If argumentsList was not passed, let argumentsList be a new empty List.
