2. Now let's create our first action creator. Every action needs a type property to define it, and actions will often have a payload property of data to pass along with the action. In this recipe, we're hardcoding a mock API response made up of an array of two photo objects, as follows:

export const fetchPhotos = () => {  return {    type: FETCH_PHOTOS,    payload: {      "photos": [        {          "albumId": 2,          "title": "dolore esse a in eos sed",          "url": "http://placehold.it/600/f783bd", "thumbnailUrl": "http://placehold.it/150/d83ea2", ...
