React hooks: accessing up-to-date state from within a callback

Question

EDIT (22 June 2020): as this question has some renewed interest, I realise there may be a few points of confusion. So I would like to highlight: the example in the question

Answer 1

The only method i know is to call the setState(current_value => ...) function and use the current_value in ur logic. Just make sure you return it back. Ex:

const myPollingFunction = () => {
    setInterval(() => {
        setState(latest_value => {
            // do something with latest_value
            return latest_value;    
        }
    }, 1000);
};
