Example 1: react hook useeffect

//useEffect it's like componentDidMount/WillUnmount
function Example() {
  const [count, setCount] = useState(0);

  // Similar to componentDidMount and componentDidUpdate:
  useEffect(() => {
    // Update the document title using the browser API
    document.title = `You clicked ${count} times`;
  });
  return (
    

      
You clicked {count} times
       setCount(count + 1)}>
        Click me
      
    
  );
