Hi @nagayev, it looks good. Not sure if we should keep both or add them to the documentation. What do you think?

[nagayev]

@diasbruno I think classes will deprecate in future, so I think we can use Hooks everyware and delete old docs.

Hmm...I'm not sure on this one, it would be great to be on the latest version of react, but this transition will take some time, and I don't how the adoption of hooks going...

Would you mind if we let this open so we can get more input on this? If we get more 👍, it will be a sign that we can move forward on using hooks.
