The useState hook is a fundamental hook in React that allows you to add state to functional components.
Explanation:
useState is called with the initial state (in this case, 0).
It returns an array with two elements: the current state (count) and a function to update that state (setCount).
You can use the state variable in your component’s JSX and update it using the setter function.
Key Points:
Initial State: The argument passed to useState is the initial state.
State Updater Function: The second element in the array returned by useState is a function that updates the state.
Re-rendering: Updating the state causes the component to re-render with the new state.
