Getting data from an API array in React

I have a React component that has to retrieve the items of an array containing objects that comes from an API. The array, favorites, is structured with items like this:

0:Object
  _id:Object
    ObjectId:"5db9cd4a1a088e7756516889"

where each of the items hold the id for a specific movie within a collection called movies. I have been trying to use map to get the data from this array with this piece of code:

{favorites.map(favorite =>
                      (<li key={favorite}>
                        <p className="favorites">
                          {JSON.parse(localStorage.getItem('movies')).find(movie => movie._id === favorite).title}

I have been failing miserably because I looked so much into this code. Could any of you throw some light in it? Any help is appreciated. Thanks in advance
