/**
 * Returns the result of applying the onSuccess function to the value inside
 * a successfully resolved promise. This is useful for working with promises
 * inside function compositions.
 *
 * @func
 * @memberOf R
 * @since v0.27.1
 * @category Function
 * @sig (a -> b) -> (Promise e a) -> (Promise e b)
 * @sig (a -> (Promise e b)) -> (Promise e a) -> (Promise e b)
 * @param {Function} onSuccess The function to apply. Can return a value or a promise of a value.
 * @param {Promise} p
 * @return {Promise} The result of calling `p.then(onSuccess)`
 * @see R.otherwise
 * @example
 *
 *      const makeQuery = email => ({ query: { email }});
 *      const fetchMember = request =>
 *        Promise.resolve({ firstName: 'Bob', lastName: 'Loblaw', id: 42 });
 *
 *      //getMemberName :: String -> Promise ({ firstName, lastName })
 *      const getMemberName = R.pipe(
 *        makeQuery,
 *        fetchMember,
 *        R.andThen(R.pick(['firstName', 'lastName']))
 *      );
 *
 *      getMemberName('bob@gmail.com').then(console.log);
