//The useState Hook
//useState is a Hook that lets you 
//add React state to function components.
//after a state is changed, the page is rerendered, refecting
//the state change

import React, { useState } from 'react';

function Example() {
  // here we declare the state variable count 
  //and its function or 'setter', setCount
  
  const [count, setCount] = useState(0);
  //It returns a pair of values: the current state(count)
  //and a function that updates it(setCount)
  return (
    <div>
      <p>You clicked {count} times</p>
		//{*setCount is the function that updates the value*}
      <button onClick={() => setCount(count + 1)}>
        Click me
      </button>
    </div>
  );
