To evaluate the value of useState that has been updated in useEffect through dispatch and payload in Redux, you can follow these steps:

  1. Define a selector function in your Redux store that gets the value you want to evaluate. For example:
const getTotalCount = state => state.totalCount;
  1. Import the useSelector hook from the react-redux library in your React component.
import { useSelector } from 'react-redux';
  1. Inside your component, use the useSelector hook to get the value you want to evaluate. For example:
const totalCount = useSelector(getTotalCount);
  1. You can now use the totalCount variable to evaluate the value of useState that has been updated in useEffect through dispatch and payload in Redux. For example:
useEffect(() => {
  console.log(`Total count is now ${totalCount}`);
}, [totalCount]);

This will log the updated value of totalCount whenever it changes. You can then perform any further evaluation or calculations based on this value.
