I'm starting with React and I need to use the 'useState()' function in a site.

First, I'm creating the useState variable: const [messages, setMessages] = useState(['1111', '222'])

Then I'm returning a div with the messages.

Up to here it's working, but I have to use my 'SetMessages' command:

setMessages(...messages, '333')

And when I write it , my site it stops working and all I see is a white page. I've seen many videos about it and I literraly copied pasted their codes them and it still didn't work, what's wrong with my code and how to use this second command from 'useState' right?
