setstate does not update state immediately

Comment

/* React’s setState and useState do not make changes directly to the state
object. Instead, they create queues for React core to update the state object
of a React component. So the process to update React state is asynchronous for
performance reasons. That’s why changes don’t feel immediate */

/* SOLUTION: However, you can use the useEffect hook to update the state 
immediately in a functional component. */
import React, { useState, useEffect } from 'react';

function Example() {
  const [count, setCount] = useState(0);

  const handleClick = () => {
    setCount(count + 1);
  };

  useEffect(() => {
    console.log(count);
  }, [count]);

  return <button onClick={handleClick}>Click me</button>;
}

/* Now the console.log statement will log the updated state value, because it
is being called inside the useEffect function with the count state variable in
the dependency array. */

//In case of hooks, you should use useEffect hook.
const [fruit, setFruit] = useState('');

setFruit('Apple');

useEffect(() => {
  console.log('Fruit', fruit);
}, [fruit])

setstate do not update emidiatly

Comment

//if some of your code depends on that state update you can use a useeffect like this
 useEffect(() => {
        if (currentProgress[index].progress === 100) {
            GoBack()
        }
    }, [currentProgress])
