useState in react.js simple example

In this example, we import the useState hook from the React library. Inside the Example functional component, we declare a state variable called "count" using the useState hook. The initial value of count is set to 0. We also define a function called handleClick, which increments the count state by 1 when the button is clicked. The setCount function provided by the useState hook is used to update the value of count. Finally, we render the current value of count in a paragraph element, and a button that triggers the handleClick function when clicked. When the button is clicked, the component re-renders with the updated value of count, and the new count is displayed on the screen.
