How to upload an array of images URLs to Firestore?

hello how to upload an array of images urls to firestore in react native i tried this 

 state = { photos: [] };

buttonPress() {

const { photos } = this.state; 

firebase.firestore().collection('users').doc('images')
.add({ photos });
}

but the image would show like this in firestore database

{
"book": "Robin hood", 
"photos": "https://picsum.photos/id/1001/5616/3744",
 }

i would like it to instead show in an array like this in firestore database 

{
"book": "Robin hood", 
"photos":  [ "https://picsum.photos/id/1001/5616/3744"],
 }

This can be achieved by wrapping the photos inside []. Therefore your code would be;

firebase.firestore().collection('users').doc('images')
  .add({ [photos] });
}

Also, incase you want the user to add later and not overwrite the array, I would suggest using set with merge: true.

firebase.firestore().collection('users').doc('images')
  .set({ [photos] }, { merge: true });
}
