React Hooks are a feature introduced in React 16.8 that enable functional components to use state and other React features without writing classes. They provide a way to manage component state, perform side effects, access context, and more within functional components, offering a simpler and more intuitive approach to building React applications.

In this article, we will implement theming and dark mode functionality in a React application using React Hooks. We’ll manage the theme state with useState and persist it using useEffect and local storage.
