Benefits of Async Await (ES7):

  • Readability.
  • Await allows you to halt the execution of the function until a resolved promise is returned.

Benefits of Promises (ES6):

  • Define arbitrary resolved value.
  • Custom error handling.

Async Await:

export function getActivityPageFeed() {
  return async (dispatch) => {
    const payload = await dispatch(fetchAPI(`/api/activity`));
    // Do something else here with resolved payload if required
    dispatch({ type: SET_ACTIVITY_PAGE_PRODUCTS, payload });
  };
}

Promises:

export function getActivityPageFeed() {
  return (dispatch) => {
    return dispatch(fetchAPI(`/api/activity`)).then(
      (response) => {
        dispatch({ type: SET_ACTIVITY_PAGE_PRODUCTS, payload: response });
        Promise.resolve();
      },
      (error) => {
        return Promise.error(error);
      }
    );
  }
}
