I'm integrating my frontend with WebSockets when I get the message I set that into const [messagesList, setMessagesList] = useState([]) state. But when I set the state and console it displays empty like [].

I'm setting the state with this method:

setMessagesList((messagesList)=>[...messagesList,{'msg':type,'user':data.text}])

So how I can update the state with the previous array of data?

Why do you think that the state is not updating? Is the new message not rendering in the UI? – Ramesh Reddy Jul 05 '21 at 12:19

you're probably logging right after calling `setMessagesList` – Ramesh Reddy Jul 05 '21 at 12:32
