title: Explanation about types of functions in react
body: <p>What's the difference between function declaration and arrow functions for create react components (Not the functions inside the component that we need to bind)! </p>
  
  <p>Old versions of reactjs when you run create-react-app, creates the App component as an arrow function!</p>
  
  <p><code>export const App = (props) =&gt; {}</code></p>
  
  <p>And the newest version creates as a function declaration</p>
  
  <p><code>function App() {}</code></p>
