React class component

The setState method is the method to update the component’s internal state. It’s an asynchronous method that’s batched . This means that multiple setState calls are batched before a component is rerendered with the new state. setState doesn’t immediately mutate the state but creates a pending state transaction.

The only difference between the functional component and the class component at this point is instead of calling this. setState we use the function we created in the useState , in this case, setValue .

useState is a Hook that allows you to have state variables in functional components . You pass the initial state to this function and it returns a variable with the current state value (not necessarily the initial state) and another function to update this value.
