Hi The Net Ninja, absolutely stunning playlist... Just a question, why wouldn't you use setReviews([review, ...reviews]) (plus the key) to add the new review instead of the anon function?

[ramziosta]

instead of Math.random you can do the following as a key genarator: const [key, setKey] = useState(1) and add to onPress : setKey(key+1)

to create the key, you could use the state you already pass in and run a compare on the title to make sure it's not present (would also make sure you don't get a duplicate title) and if it's unique, md5 hash that and use it as the key.

The way I would prefer so you get an iterative key (much better for searching if you have to later) is to add an "ID" key to the object, then when adding an object you just make the key the props max key +1

Hope that makes sense, youtube comments aren't friendly to pasting actual code, would have preferred to post a code example
