# Class Components
In the previous sections, we have covered JSX, functional component and props. In this section, we will cover class components or statefull component. Only class based components used to have state and life cycle methods. However, after React version 16.8.0 functional components can have state and life cycle using React Hooks. In 30 Days Of React challenge, we will cover React before 16.8.0 and after, that mean both old and newest version. There are lots of codes written in older version and at some point it may need migration. In addition, to understand React very well someone has to understand class based component too.

All the previous components are functional components. Let us make also class based component. Class based component is made using JavaScript class and it inherits from react Component. Let us learn how to make a class based component by converting all the functional components we made previously. It is not important to convert all but we are converting them for the sake of learning how to change functional components to class components.
