🦉 You can observe that when we're talking about "state" we're also talking about keyboard focus as well as what text is selected! As you play around with this, try selecting text in the inputs and observe how the first two examples differ from the last one. You'll notice that using the array index as a key is no different from React's default behavior, so it's unlikely to fix issues if you're having them. Best to use a unique ID. Play around with it!
