react native function component after render code example

Example 1: react useEffect

import React, { useEffect } from 'react';

export const App: React.FC = () => {
  
  useEffect(() => {
        
  }, [/*Here can enter some value to call again the content inside useEffect*/])
  
  return (
    
Use Effect!
  );
}

Example 2: component did update hooks

import React, { useState, useEffect } from 'react';

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`;
  },[count]); // use dependency array to watch for state changes on this part of state

  return (
    

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