title: React App with both Functional and Class components
body: <p>I know that after the emergence of <strong>React Hooks</strong>, functional components are able to act almost the same as the class components, and I have seen lately an encouragement wave to use functional components.</p>
  
  <p>My question is, could it hurt in any means to have a hybrid react app with some functional components and some class components? I understand that react would not complain about it, but I am looking for an experienced best practices, did inconsistency with component's types cause any problems?</p>
  
  <p>Any tips are appreciated.</p>
