React 16.8 introduces users to the concept of hooks. Hooks allow the consumption of state and other React features without writing a class. Not only that, but it allows developers to build their own hooks and share reusable logic between components.
Please note that these hooks are only available in React 16.8. Our project is built with 16.6.0. So, if you want to use hooks, consider upgrading to 16.8. By now, you know how to create a new project. You can read more about using the hooks at https://reactjs.org/blog/2019/02/06/react-v16.8.0.html.
