react useeffect called every render code example

Example 1: use effect like component did mount

useEffect(() => {
	console.log('I am the new componentDidMount')
}, [])
// Don't forget the empty array at the end

Example 2: react hook useeffect

//This is a basic example, carefully read the docs as
//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 (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>
        Click me
      </button>
    </div>
  );
}
