I’m trying to build chat application using firestore and i want to get the latest value from array. How can i call it from cloud firebase.

 const unsub = onSnapshot(doc(db,'chats', userID), (doc)=>{
      if(doc.data()){
          setLastMessage( doc.data().messages )
        }
      })

      return ()=>{
        unsub()
      }

Currently i’m calling just an array. But i need to call the lastest value from it. Also the data in firestore looks like this:

messages: [
    0: {
       id: uuid(),
       text,
       senderPic: currentUser.photoURL,
       senderId: currentUser.uid,
       date: Timestamp.now(),
       },
    1: {
       id: uuid(),
       text,
       senderPic: currentUser.photoURL,
       senderId: currentUser.uid,
       date: Timestamp.now(),
}
]
